They offer coupons on the back of your HEB receipt for $10 off, yet they give you only $8 off. They refuse to honor their PRINTED coupons! False advertising and deceptive business practice. The employee said "their register won't allow them to give $10 off; and the boss won't either." Shameful. It's not about measly $2. It's about treating your customer right and honoring your own damn advertising. This isn't the first time they've done this, but this is the last time I'll patronize their business. read more

Grand Slam Car Wash - Their coupon - Car Wash Near Me - Cypress, Texas

Classic bait and switch. None of the prices on the website are honored at the Grant Rd location. I came in for the $60 Super Clean package, and it immediately jumped to $80 with less included in the package. Judging from the other reviews, I'm happy with the fact that I left when the approaching employee (who found it completely appropriate to lean his greasy arms on the passenger side of my truck as he leaned into my open window) told me "Those aren't OUR prices." Pass. read more

I have been getting the Home Run pkg. for 4-5 years-it started with a Groupon with great satisfaction! I was concerned that after the Groupon stopped it would be pricy and looking at the reviews wasn't sure. So, I tried it again recently and was amazed that the pkg has only gone up a few dollars from the Groupon pricing and the service was the same great quality as before! They vacuumed the car well and it went through the wash and dry machine. Then 4-5 people immediatley began doing the windows, wiping down the interior with a special leather & cleaning treatment for the dashboard, cleaning the wheels and shining the tires all within minutes! This is an amazing value and service. Thank you Grand Slam! read more

Very thorough. For $65, outside wash and detailed interior clean. Very happy with the service.

Second time I've tried this place. Still disappointed. They do NOT detail like they claim. $60 later I still need to vacuum, clean out the storage in the door, clean the wheels... all things that should have been done with my package. I won't be back unless it's free!! read more

I had my jeep detailed and they did a great job and paid attention to the little details also. The supervisor even came over close to them finishing and double checked everything. read more

I love this place! They always do good work. I will tell you that there are negative people out there who expect their car to be cleaned fast and that's not how it works. Bring a book and chill out while someone else is doing your dirty work. read more

Wow! Your website clearly shows that a Single car wash is considered Full Service Option but you will not honor a $7 coupon that clearly says ANY Full Service Wash. You just lost a customer that's been coming here for 15+ years. read more

Grand Slam Car Wash - Car Wash Near Me - Cypress, Texas

I dropped my car off at 11 and went to pick it up at 3:30 because the hours of operation are open until 5. They have closed the shop for the day and no one in the office to give me the keys to the car. This is unbelievable and now I have no vehicle to get to work with in the morning. read more

I am done with this place. There is always an issue here. 3 weeks ago I brought my daughter's car here to get washed. I picked the most expensive wash they had. The car was pretty dirty. I left the car and told them to take their time and that I would be back for it. Came to get the car and the carpet had been vacuumed half assed. I had just paid $140 and they cannot even vacuum it right!!! . Also when I tried to pay, I had a $50 gift card that I bought from them, they told me it wasn't good. ‍ Today I come in to get a simple wash, $20! I brought a coupon. They refused the coupon and charged me $2 for an oversized car. I drive a small SUV!!! I'm done with this place. I hate nickel and dime places. Not coming back. read more

My first visit here (May/June 2021) was such a pleasant experience. I loved how clean my vehicle was and how quickly it was ready. Service has severely declined since then. I had a membership from June 2021 - Dec. 2021; canceled because the quality of service was not getting better. The exterior cleaning process was consistent but the interior cleaning was terrible. I let a sales representative know I wasn't satisfied and canceled in December 2021 but I was still charged in January. After speaking to the manager, she said she wasn't notified of me wanting to cancel so my membership was still active. She was able to cancel my membership that day (mid January 2022) but stated she couldn't refund my $50 membership fee. We tried to come up with solutions because it wasn't my fault she wasn't notified and I didn't want to leave my $50 chilling in their business account. She offered me a detail to compensate for the erroneous fees I incurred. I then tried to explain that I'm canceling because I'm not happy with the cleaning service; being compensated with a cleaning doesn't make sense. In the end my only option was accept a "detail" priced at $70. At this point I'm feeling a bit aggravated so I accepted. Fast forward to April 2022, I'm returning to receive my compensation detail. THERES A NEW MANAGER (NM)! This new manager (NM) has never seen me and doesn't know what I'm talking about. Luckily, I see the sales representative that is familiar with my situation and he explains to the new manager(NM). Things still aren't working out with this NM but he does offer 50% off the detail and guarantees satisfaction. The detail is now priced at $80 so I would have to pay $40. Don't forget that I've already been wrongfully charged $50 for a membership that I cancelled. Once again I'm in a situation to spend/lose money at this establishment. Here we go!! The NM seems to be a cool guy so I reluctantly accepted the 50% off deal and sent my car to detail. Now I'm at $90 that I never should've spent here. The exterior cleanliness of my vehicle could be rated at 8 of 10, due to the wheels not being really clean. I would rate the interior cleanliness at 6 of 10. This service was rushed and not taken seriously. There's still lots of grass and debris on my floors. The dash board has excessive amounts of cleaning solution left behind. My cloth seats were not vacuumed. I can never return to this place and would deter anyone who cares about their vehicle to go elsewhere. read more

This was my second visit. First was ok. This time, The man tried to upsell which I declined but since I wanted the mats washed, he said it would be $45 package which i was ok with. I insisted they clean the inside well and not care much about the outside coz it was going to rain anyways. The interior was still very dirty. The mats not washed, so upon complaining they took it and dry brushed it. The seats were not vacuumed, the dashboard was not wiped and basically except running it under the automatic car wash, they did nothing. This i could have gotten it done for $8. I wanted to like it coz it is close to my work so i could go during lunch break but I will not return. It was a waste of the $55 that I spent. read more

This is just another update on why you don't need to give this place your business. Decided to give them another shot for the convenience factor alone. Drove up and 4 cars waiting for service and absolutely no one in sight. Waited a few minutes and still no one around. Some dude in a bmw was looking around for someone, but this place has burned me before so I just turned around and left and went to whitewater. At least they have folks outside when you pull up. read more

I want to start off by 55$ for a "super clean interior" definitely not what they left my car with... super clean interior comes with "* Home Run Wash * Thorough Vacuum Of All Interior Cracks & Crevices * Under Seats Blown With Compressed Air * Degrease & Disinfect All Plastic & Leather Surfaces * Leather Conditioner Applied To All Interior Surfaces" well unfortunately for me I didn't notice how terrible they did until I got home literally doesn't look "thorough vacuumed" honestly doesn't look like they vacuumed under my seats at all either. When I picked up my car there was a footprint.. seriously after cleaning it just for them to leave it like that? I would go somewhere else read more

$200 detail they had the truck for 2 hours. When I picked it up bugs all over the grill, bumper and mirrors. Leather had been wiped down but not in the cracks, paid for a wax but when I asked about it and showed the manager the dirt that wasn't removed he had them do it again. Waited another 30 minutes. It was a $200 car wash until I complained. I should have checked yelp first! Just another $200 1 star performance. read more

Someone stole my beats and windshield wipers that I was planning to put on my windshield. They made the effort of going into my backpack and taking my beats headphones. That is ridiculous. Need to hire better employees. read more

They are "OK". But in this area there's too many other options to just be OK.If you're looking for a place skip grand slam. Ricky, I found your email in another post and will email you more details. read more

had a membership for my miata. since i was about to travel i asked if the charge was 'automatic' and was told (by the inside attendant who looked up my license plate) it was not. low and behold May and June were charged. i stopped by to ask for a refund and was told 'we don't give refunds' and that i had to get my bank to stop the automatic payment... well i've disputed the charges with my Bank but there is no way the bank can stop the auto billing by the merchant. unless i find a way to cancel my account i'll just dispute every month. my advisce is to avoid memberships at this car wash. read more

Been here a couple times. They never do a good job and they will steal anything of value you might leave in the car. Be wary.

My first and last experience at Grand Slam Car Wash was absolutely horrible. I do not appreciate any type of business that takes clients money without doing the work. I left their facility with dirt water in my floor matts that wasn't there prior to the cleaning. They did not vacuum under the seats, did not wipe down the interior windows, did not wipe down the cup holders or doors. When I immediately turned around and went back to inform them of the missed cleaning areas, they laughed and I was given no apology. The staff was rude and unprofessional. They began to clean the areas missed and then continued to laugh without taking their business serious. I will not refer anyone here for future business. read more

This place is over priced, they take way too long to wash your car and don't provide what their pricing says. There are plenty of other car washes in Houston that are a better value and do a much better job. read more

I thought I'd try a new car wash on a Thursday afternoon. There weren't too many cars/trucks in line (4?) - and yet it still took over an hour before I got my keys. This is poorly staffed, poorly managed, and to top it off, the wash job / hand dry was mediocre/poor. There were MANY bug splats still left on that were easily removed once I got home. They also left numerous streaks. For $50 I expect better. A lot better. read more

Just not courteous or well organized... Lost keys for someone's car while I was there. Put all the mats in backwards after cleaning. Store looks cool and the wash wasn't bad but the experience is not as friendly as it has been before the new owners. One more shot and down the road I go read more

Have not been here in a long time. Needless to say I won't be back after trying them again. Seeing the same issues as I did last year! Car wash machine kept on stopping and they still are shorthanded. Been here 15 minutes and my car still has not made it through the wash. This is on a Thursday evening at 5:30 pm! read more

Rude custom service. Cashier was making rude looks. Car was barely wiped down.

Ig Pa've used this carwash for the convenience factor for awhile now. I just didn't have time to find a different one. But this last Monday I was pleasantly surprised when I pulled up and asked for the Extra Interior Cleaning Package. I've never purchased this package before and usually just get the basic service. But this time I was desperate to get all of the dog hair out of my car. I talked to the girl at the desk asking if they would be able to do it since they were busy. Much to my surprise, the manager stepped in and made sure it all went as it should. He actually followed my car all the way through the process and checked it himself when it was done. I have to say, I'm not usually overly enthused with the service there but something has changed. I was pleasantly surprised to see that they did do a great job, especially since I had paid extra. This time it was an actual homerun! Great job and thank you so much!! read more

Great place for a good quick car wash! The place is always clean and full of friendly staff. I've been coming here for a few years now and I've never had a bad experience. read more

My favorite car wash! Have the for treatment done on a Saturday evening. There were even scuffs down the side of my driver's door from a previous mishap. And even though they were slammed at the time the crew still made the effort to get the scuffs off and give me a perfectly clean car. I recommend Grand slam to everybody! read more

Liked them at first but quality is going downhill with new owners and uninterested employees. I'm hating always asking them to finish the job. Will be going elsewhere. read more

I have no problem with the quality of the wash, but I came here in the middle of the day during the week with only one car in front of me and it took FOREVER. From the time on my receipt, to when the car entered the wash bag it was 38 minutes. Then only another 5 minutes to rush the interior cleaning and windows. Nobody has that sort of time for a wash, especially when the interior is rushed. What in the world was going on for the first half hour? I could have done the whole thing by hand in half the time. read more

I truly feel like they make up their own pricing. I went one day and they told me $80 but it would take up to 3 hours. I didn't have time and came back the next day super early and the guy looks at the car and says $120..... yeah no. It was a small Toyota Prius and just needed interior detail, no stains. read more

Took our car there today.... They do a good job on the exterior, but really don't do much on the interior. Crumbs still on the seats and not sure what they wiped down on the interior. Will just do it myself next time.. read more

I come here all the time and it's just like any other Houston car wash. If you want a perfect Carwash I'd purchase a hand wash. My car requires a hand wash anyways so that's all I've ever had. read more

Great service and cleaning. Have been coming here since they opened. Courteous staff. Great attitude.

They do a horrible job. Terrible vacuuming . Even in the third try they couldn't get it right. Complained about how they can't vacuum up sand! First time they did not even vacuum out the back even though they charged extra for a small SUV. Back bumper still filthy. Never stepping foot in here again. Refused refund when vehicle was still not clean. Manager not available and unable to provide contact information. read more

I recently got my car washed here and they rip and piece of my Tahoe off and then said it wasn't them. I have explained that when I arrived it was attached and now it's not. They still won't pay even though they have video of it. Don't waste your money here or you will be wasting a lot of time fighting with them. read more

I am not from the Cypress area but I needed a quick car was and vacuum. The service was great, the place was clean.

Save your money!!! I have toddlers that could do a better job. They are in my neighborhood and I have given them 2 chances and sure won't give them 3. After spending $30-40 each time, car isn't ever vacuumed well and anything called clean/condition interior and tires is never done or not done well. read more

Worst car wash I've ever had. Paid for the Single and just about the only things that were cleaned were the tires. Water spots everywhere, no inside wiping (still had dust on the dash and in the cup holders), and a half-rate job vacuuming. The guy "drying" the truck actually use WINDEX on the paint to try and get some of the water spots off. I left with water spots all over the windows, mirrors, foot rail, and paint (where he didn't get to use Windex because I told him not to). No rush to get the job done either, which is surprising considering the quality of the work that was done. I will absolutely not be back! read more
