After repair work.

I would strongly NOT recommend cornerstone construction as we were completely unsatisfied with repair work done. Also, several promised repairs were not completed and when confronted about promised repair work not completed cornerstone construction was dishonest and denied conversations ever took place. There was a severe lack of pride with repair work too, as photos will show. Company in my opinion has a lack of integrity and poor work ethic. Repairs were done in a hurried manner and end result looked horrible!! Some repairs were never even done!!! I would strongly urge one to look elsewhere when looking for any type of repair work to be done. Save yourself heartache and frustration. So very disappointed in cornerstone construction!!

Cornerstone did a wonderful job updating our molded tub-shower.  We love it!

See all

If I could leave 0 stars I would. Got an epoxy floor done through this company in February and I…read morewouldn't recommend them to anyone. First I dealt with Matthew who was the project manager and completely dropped the ball on this project. A month after installation my floors started lifting and he tried to tell me it was a plumbing issue & a leak in the floor and it wasn't a floor failure. Had a plumbing inspection done and turns out there was no leak. Reached back out and he never got back to me through text or call, so I wrote an email. Then I get a text from Walter who said he's the owner and knew nothing about the project but saw there were issues & informed me Matthew no longer worked for the company. He was very on top of it, came in to look at the damages, paid me back for the plumbers to come out, told me he would make it right & fix the floors. Scheduled the floor repairs for August 9-11, tried getting ahold of him the week before he was supposed to come in. Phone is off, and never showed up to fix the floors. Even emailed the email on his business card and nothing. Completely unprofessional especially when he was so on top of it to make it right to just ghost me and never show up or even contact me. Use someone else, save yourself the hassle.

Amazing!! Service, quality and value In November 2024, we…read morepurchased a investment property in the city of Hesperia, California intended to be used as a (short term rental). we have established several short term rentals, different counties of Southern California, however, we have found it very difficult finding reputable contractors to work with. This has been a challenging task as we have encountered contractors of all sorts, making promises only to fall short of expectations. After receiving several estimates, we decided to use Modern Decor Interior. From our initial consultation, Walter was very knowledgeable, professional and informative about the renovation that needed to take place. We decided to add a separate dwelling unit (ADU) Walter handled everything from architect to engineering dealt with city inspectors you name it or experience with stress-free and our final outcome was amazing. Walter and his team were very communicative as well as efficient and professional. Our job was completed before schedule and it's already generating revenue for us. I couldn't be happier to have found such a professional trustworthy company. Walter is amazing and patient a very knowledgeable contractor. I've already recommended Modern decor Interiors llc to a couple of colleagues and plan on using them all my future projects. These guys did not just meet my expectations. They exceeded them in every way possible! I would read them at 10 if I could to explain the whole process will take 3 to 4 pages ! We had great customer service great value overall her price was not the lowest as other estimates however it was realistic and on budget project was completed on schedule and be on our expectations. Our overall scope of work was a complete interior and exterior renovation as well as a ADU addition . My personal experience was awesome. I would highly recommend them 10 out of 10.
