Vinyl Siding - Install or Completely Replace
$35,000
It was an absolute pleasure working with Nonstop Home Improvement. Right from the start Deniz made us feel comfortable, was completely transparent in what to expect what could come up as we moved along in the process. The crew was amazing, courteous, and thoughtful in providing solutions to unforeseen issues with the house’s structure as they came up. We couldn’t be happier with the results. Everything looks mint, brand new and clean, like a new build basically. We’re only day two finishing the job and countless neighbors and people passing by have asked who we used, house looks great, all the things and it’s a good feeling. I highly recommend working with Nonstop Home Improvement for your house’s siding and roofing needs.

Deniz and his team did a great job on my roof. His price was fair, they were on time and did what he promised, and went above and beyond with the rot that he found under the siding around the dormer. His team picked up after themselves so you would never know they had been there. I highly recommend him.

I can’t say enough how great Non Stop Home Improvements Inc is. Dennis and his men were clean, respectful and on time everyday. My roof, siding and door are a beautiful addition to my house. Dennis answered every question I had, and every text that I sent him. I would highly recommend this company for any contracting needs.

Nonstop home improvements were great! They were recommended to us, and I would highly recommend them as well. They thoroughly took care of us, addressing any concerns we had and made the roof replacement easy. They tore up two layers of shingles, replaced the wood underneath and layered new shingles. All for a fair price!

Needed a difficult (cedar shake) roof replacement on very short notice. Deniz (owner of business) was amazing to work with. No complaints at all. He was great with communication, clarity, quick to respond, and his pricing is great. Everything that was planned for happened the way he said. Crew came in on time, worked incredibly hard and fast, and job was done in a day. It also speaks volumes that as the owner of the business he is not only onsite for the job but actively helping out the crew. Couldn’t ask for a better experience and couldn’t recommend Deniz and Non Stop Home Improvements enough. Will be using them going forward and recommending them to anyone in need.

It's a great experience. The roof and siding are done professionally. The team is efficient, works on time, and clean up at end of work day. The price is reasonable, and the owner goes above and beyond to troubleshoot any problems. They also pay attention to small details. The house turns out much better than I expected. I am glad I didn't go with other big companies. Highly recommended! 10 out of 10!

Great job by Deniz and his hard working men. I had to go to work when they started but my retired next door neighbor watched them and told me they worked almost non- stop on a very hot 93 degree day. I would highly recommend Deniz to anyone looking for high quality roof work.

If you are looking for outstanding customer service (which is a dying service in the US), quality work and the right price, then Non Stop Home Improvements is the company for you. We interviewed 5 contractors to vinyl side the house and the prices fluctuated wildly. Non Stop was the last contractor we saw based on a recommendation from someone I trust. Deniz's work was first rate. He found items in the siding that needed to be addressed that no other contractors saw. In fact he went above and beyond what was expected in the contract. Highly recommended. My search for an excellent contractor has ended. Deniz and his crew will do any of our work on the house going forward. He was that good! And my thanks to the friend for recommending Non Stop.

Deniz returned my call right away and stayed in touch when the schedule had to change because of bad weather. He's an expert at what he does and freely shares his knowledge. Deniz spotted the source of the leak right away. I will definitely call him again. His price was fair, and he's a pleasure to work with.

Estimate: On time & not a waste of time. Accurate estimate and willing to match legitimate competition. Agreement: Clear communication of product, timeframe, warranty, and work to be done. Work: As scheduled, clean, neat, attention to detail, and overall quality work. Deniz is a professional and master at his craft. He takes pride in his work and will make sure the job is done as best as possible. As a potential customer and eventually a customer, I felt like I was a priority at all times. He has a great relationship with his crew and they are hard working which is great to see. I highly recommend working with Deniz as he is one of the rare "old school" honest and reliable businessmen I've dealt with as a homeowner.
