General Contractor reviews in Bronx, New York

Greystone Construction installed paving stones around our house. The did an EXCELLENT JOB and were quick, efficient and very punctual. Overall the work was done in a timely manner - TOP NOTCH WORK! I highly recommend them - call Omar at Greystone CONSTRUCTION and you won’t be disappointed.

We just had our entire backyard raised by a foot to prevent flooding -- something we wanted to do for ten years now but had held off because we felt it would be too expensive and complicated. The side wall of our home was waterproofed down to the foundation and a new driveway was poured. Plus grinding and pointing, sealing and painting. The work was done by professionals who communicated with us clearly every step of the way. We couldn't be happier with the results, and we now have peace of mind. Thank you, Greystone.

I hired Greystone Construction Group, and they were amazing! Umar was very responsive and cooperative throughout the entire project. They installed stucco in the basement and garage, applied paint afterward, and even fixed the cracks all over the exterior walls. I’m so happy with the results and will definitely work with them again. Highly recommend!

I decided to have paving stones laid down in my back yard…..When I tell you these guys at Greystone are amazing they are AMAZING!!!! They do every kind of work imaginable and then some. They are on time and work very hard!! They get straight to work upon arrival and don’t stop until the work is done!!! I love these guys and I’m calling them back to do work on the inside. Greystone comes highly recommended!!! They even painted my shed!!! See you soon Greystone!!!!! Give them a call you’ll be glad you did!!!

I had an overall great experience with grey stone construction. Omar was very responsive, had great pricing, and implemented all of the details that I wanted. I needed to contact Omar twice after the job was completed for some minor tweaks to the job, but he was very responsive and his workers were able to correct the issue promptly. Some advice would be to cover any grass around the working area as concrete can be quite messy.

Contracted keystone to install pavers in the backyard.they did a excellent job.they was on time and cleaned up nicely when finished. Seasonal price and good worker.

Keystone Contracting went over and beyond the work that was needed for my roof repairs...they visited at least five (5) times until the problem was corrected while keeping in touch to check if I had any issues

Excellent customer service , would definitely recommend

I had the sidewalk repaired by the driveway. The guys did a nice job and were very nice. I would use them if needed. The price they gave was very affordable.

We have had a very good experience with Keystone Contracting, they repaired and painted our Chapel. Responsible and serious people. Thanks.

Hired keystone to do concrete work and build a planter.. they were excellent. Cheaper then all contractors on home advisor and good at what they do...

Keystone did a great job cutting our stone wall and installing 36” steel door. The business owner Adam gave me a really good quote compared to other contractors and kept his word. They showed up on time, kept the space clean and even gave me a discount at the end of the project. His guys’ Craftsmanship was good, and I didn’t have to worry anything. I will work with them again when we have next project.

Keystone Contracting is a professional company. The manager was responsive and provided excellent service. I would recommend this contractor for home improvements.

Adam the owner of Keystone was a pleasure to work with. Adam is conscientious and detailed and his workers are diligent and friendly. Keystone shows up to work and they get it done. Thank You!

Keystone is committed and dedicated to their work they keep to their time frame The roofing repairs has been perfectly made and there is no more leakages They are good construction partners.

I hope I can save someone else the trouble of dealing with this company. I don't know how they could possibly have a 4.8 rating. It's too bad I cant give them 0 star review.

I called them to make an appointment for an estimate to repair my skylight leak on Thursday. They told me someone would come after 2pm, no show, no call. I called Friday morning to find out what happened, spoek to a Michelle, I got an apology, but no explanation. They offered to come back out Friday after 4pm and I thought I'd give them a 2nd chance, things happen after-all... I waited, no show, no call. I called the office back 2x got no answer.

Then late Friday evening I get a call back, asking me if I had called about a skylight. I was asked to text the pictures of the damage to them, so I did, again no response. So now the light bulb is going off in my head, these guys probably don't want to waste their time coming out. Fast forward to Sunday, I respond back to my last text waiting to see if I get an answer, I get "We sorry about it' just unusual situation because of Covid, but it seems like something minor we can seal around skylight for $550".

Are you for real??? How do claim to be this great a company, and provide an estimate via photo for a roof leak?? I'm no roofer, but you gotta see a problem like this in person to make a good judgement call on whats causing it. Photos only tell part of the story.

Don't waste your time with these guys. I bet a lot of these reviews are lies. Any good roofing contractor will go up and look at the damage, not guestimate via text message photo. Poor communication skills, poor follow up and poor overall experience. I would never call these guys for anything.

I feel bad for giving 3 stars, because they really did a good job in resurfacing my sidewalk. But when my husband contacted them and explained what he needed, they said that they would help him to remove the DOB violation, but actually they didn't. After the job was performed (and they got paid), my husband called to ask for help and the owner always says he is too busy and he will get back to my husband and he never does. Even though when my husband said he would pay him extra to get the DOB permit. So, that being said, the aftermarket customer service sucks!

Personnel at Keystone Contracting Corp we're outstanding and professional. We were very pleased with their work (Concrete sidewalk Replacement) and everything was done as we expected.

I had leakage in my ceiling from the snow storm. Frank came the day after I called. He was pleasant to work with. Got the job done within a day. He claims that if anything happens to the roof, he will come fix it for free.

These guys are kind, mild and easy to work with. Adam really takes the stress out of the project. He knows his business but most importantly how to treat people. Use them. They are reasonably priced they answer all your questions and are accessible.

Excellent contractors. Did pointing of the brick walls and repair an big lack of my back yard and repaired metal railings, cornice some plaster work and painting in my vestibule. Very good. Attentive and good costumer service. Can't say enough good things about them!!!

Had walkway and driveway apron replaced 3 yrs ago. Adam was the sales rep/foreman. Contract said 4” thick walkway 6” apron. Cracked within the first 6 months. Took Adam more than a year to return to repair. Now less than a year later , surface of the repair is crumbling!! Where is this company’s integrity?
