Constraction reviews in Canonsburg, Pennsylvania

A very professional company! Chaz Knox came to our home for an estimate on new vinyl siding. We were extremely pleased with the price and his knowledge. The crew did a fabulous job on the install. Tom was courteous & answered all my questions. He is a well skilled vinyl installer & we're so pleased with the results!! Ryan and Billy are hard working young men. They worked diligently in cold weather & seamlessly as a team. We are so happy we went with Knox Construction & highly recommend.

Chas Knox and his team have earned a 5 star rating from my wife and I. They checked all the boxes and more for us. Every man on their team, and I mean there were 10 of them here, were very polite and courteous and they worked hard and steady like a well oiled machine. 33 square on the house roof and 12 on the garage and they ripped off the old shingles and had the new installed with ridge vents in 6 hours flat, and that included a half hour lunch, we’re we got to mingle with the crew, and total cleanup!
Highly recommend these guys! Thank you Chas, Joe , Ura and all you other guys!!!

Knox Construction came highly recommended to me by a friend who had a vinyl siding installation done by them. I was not disappointed. From my initial phone inquiry to a friendly and courteous Tina Knox and several equally great follow-up conversations with owner, Chaz Knox, I was convinced that repairs to my wind-damaged back porch would be handled very professionally and successfully. Tom Murray was very easygoing and polite while coordinating the on-site repair work. Tom was also very thorough in clearly explaining the necessary repairs and he, Billy, and Ryan did a super job in a very timely fashion. They even cleaned the porch gutter without charging a fee. I was very impressed and pleased with Knox Construction and plan to contact them for another home improvement project later this year.

The crew from Knoxs was professional and on time. They communicated clearly and answered any questions I had during the process. They cleaned up during and after the roof replacement and explained the details of their warranty throughly. I’d highly recommend their team for any roofing needs.

Chaz was professional fair price too completed our garage that another contractor screwed us by taking money and not completing job . I’ve referred Chaz everyone loves his work. If looking for honesty in a contractor CALL CHAZ

Chaz Knox and his crew did a great job. His crew was fast, efficient and well coordinated. I spoke with several of his crew and all were polite, easy to converse with and attentive.
The clean up was first rate. They did not damage any landscaping or plants. I could not find any debrie left behind.
I misunderstood one aspect of the quoted work and when I discussed it with Chaz, he offered a very amicable solution. I even made a mistake on information I provided to Chaz regarding the gutters. Chaz again offered a solution like a true Gentleman. I was well pleased with our interactions.
I offer the highest recomendation to anone considering Chaz and his crew.

True professionals! Chaz, Buddy, and their crew understand their roles in their company and are each masters at their craft. The team from Knox's Construction do the highest quality work I've seen and offer a warranty to back it up. In replacing our roof and adding gutter covers (and some water-damaged boards underneath), they showed a unique combination of efficiency (2.5 days start to finish), carefulness (we found not one nail left in the ground after they finished), and kindness to my family and to one another. It is refreshing to see a team enjoy their hard work. Chaz was also a man of his word, and someone I won't hesitate to trust with any of my future projects. Well done men!

I had a great experience with knox construction for my new roof. Chaz met with me answered all my questions and followed up negotiating a good deal for a quality service. Casey was excellent at communicating the project from start to finish including an unfortunate rain delay. The crew completing the work was kind, courteous and did a great job cleaning up and completing the work In the time frame provided. My estimate was spot on no unexpected surprises. I would be happy to recommend them and use their services in the future

Had a great experience with Knox’s Construction to replace my roof. They were quick to respond to my inquiry and their sales guy, Armand, was super professional and never gave us a hard sell. The crew was fast and efficient, and when they uncovered some underlying damage when removing the old roof, Casey was quick to call and let us know how much the repair would add to our total. Once the job was done, the crew cleaned up quickly and left our place clean and tidy. I will definitely contact this company for future work on my home.

Knox Construction installed a new roof on two of our HOA community buildings. The work crew consisted of local workers who were professional and courteous. The work crew was efficient and worked well together The work started and finished precisely on the schedule provided. The attention to detail included taking time to do the flashing properly around the chimney, and putting sufficient plastic sheeting around the building to catch all of the nails and debris.

The roof looks great. A post-installation review by our maintenance staff found that everything was installed properly and fully with no short-cuts. Our community HOA is highly satisfied with the quality of the new roof, the efficiency of the process and the workmanship of the crew.

Very good experience. Armand gave me a very reasonable price and a detailed proposal, He asked for no money upfront. That was surprising in itself. Casey was the manager who arranged everything else. The crew was prompt, polite and worked diligently to replace my roof; they didn't use a hard sell approach, didn't try to up-sell me and the price quoted was the price I paid. They installed high quality Certainteed shingles and made sure that my property was covered by tarps. Clean-up was excellent. Over-all a very good experience. I recommend highly Knox's Constrution. Five stars! Thanks to Armand, Casey and their crew.

On a scale of cotton candy to Brussels sprouts, Knox's Construction is a perfect loaf of sourdough bread. The ingredients are simple, and the results are magnificent.

My interaction with Knox's Construction started when I found a recommendation for this company on Facebook. I called asking for an estimate. Chaz came out to check out my roof and talk through my questions. Once I signed, I was contacted by Casey who scheduled the dumpster arrival, material delivery, and roofing day. The crew that came out was professional, considerate, and hard-working. I also appreciated Theo who was communicative about the process.

The team also installed a new bathroom vent for the upstairs bathroom so that it is properly vented now.

A big shoutout to the whole team for providing a great experience and being communicative about the process and expectations.

As a home owner for over 24 years and real estate agent, I’ve had my share of contractors do work for me and/or my clients and it can be very stressful because you may not know the quality of work and/or sincerity of the contractor you’re dealing with. I can truly say that I am pleased and so relieved with the job Knox did on our home.

We had some siding blow off from a storm and our neighbor actually recommended Knox because of their quality work compared to other contractors. Chaz, the owner, Tom, the project manager and their entire crew were awesome. The quality of work is unmatched. The crew was on time everyday, very respectful, cleaned up after themselves and the attention to detail blew me away.

They stand by their work and I will be happy to recommend them to neighbors, friends, family and clients.

Knox Construction was great to deal with and I highly recommend them. Chaz, the owner was terrific. He provided the best price with the very first quote. The workers, lead by Billy showed up on time, worked full days and did a very professional job. I am very happy having done business with Knox.

Caleb helped me a great deal, showing how they would replace my gutters and downspouts, and how best to repair and replace some damaged or missing soffit and fascia.

Tom and his crew were great. They only took a day and a half. Their work was top-notch! Cleaned up everywhere perfectly afterwards.

I am very pleased with how everything turned out.
Would highly recommend them!

We had our roof replaced, gutters replaced with leaf guards, and new sky lights in December 2025.

Our roof was replaced following a heavy snowfall. We voiced concerns that the snow would make it difficult to appropriately clean the fallen nails and bits of metal that inevitably result from roof replacement and which would pose a safety concern for ourselves and our dogs. We were assured that tarps would be utilized to prevent these from being left behind. I will say that the workers tried to use the tarps, but they did not catch all of the falling nails and bits of metal, many of which we are still finding scattered around our yard, driveways, and back patio. We were told that it is typical for a cleanup process to occur following the project completion in an attempt to collect any residual hazards, unfortunately that could not be performed in our case due to the snow. Exactly what we had voiced concern about in the first place.

We had a second heavy snowfall on New Year’s Eve. The day after, we noticed icicle formation on one of the new gutters and water running down the side of the gutter creating an icy patch on our driveway. At the time, we thought this might mean that the gutter may need inspected. In addition, we found a second gutter running down the side of the house that had begun to pull away due to a loose anchor. So, I obtained pictures of those areas and sent them to the phone number that was on the roofing contract. We had hoped that someone would eventually get back in touch with us so that the gutters could be repaired and inspected. That very same day the owner Chaz did get in touch with us. Unfortunately the interaction was entirely unexpected and unprofessional. Chaz had returned our message with a phone call to scold us for contacting his private phone . When I attempted to explain that I did not realize that this was his private phone number, he continued to scold me for contacting him while he was on vacation. I certainly would want to respect somebody’s privacy and time away, however I will point out once more that this is the number listed on the contract. It does not state that this is his private number and there would be no way, to my knowledge, to have known that I should not be using this number to contact the business.

Overall, the interaction was unfortunate. I would have given this review less then three stars based on this interaction with the owner, but I do not feel that that would be fair to the workers on our project as I found them respectful and hardworking.

This was an easy 5 ⭐ review as Ryan & Liam have completed multiple projects for me at my home over the last year and I have even more work for them to do this spring including concrete driveway, grading, and a French drain.

They are professional and timely with their work. Ryan is really great with communication compared to other folks I have had do projects for me in the past which is great with my work schedule.

Ryan and Liam both have a great ability to teach and really let me understand different aspects of the projects as they were complex and some changes had to be made.

Jobs Completed:
1. Large Front and rear retaining walls with large Rosetta 🪨 stones.
2. Drive way extension with parking pad.
3. 1200sq stamped and stained covered patio.

Ryan and Liam are straight shooter and local to Canonsburg. If your looking for someone to trust with your work give them a call. I would be happy to be a reference for them.

Very professional and honest. Hard workers and Great turnaround time! Highly recommended!!

Fabulous work. Would not hesitate to recommend.

RH Landworks installed a retaining wall for me. They were professional, timely, reasonable in price, and the wall looks great!

RH landscape did a wonderful job on my sidewalk! Great work, very punctual, informative, reliable. Will have them again for any further work I need! Highly highly recommend!!
