“Depending on where you are, I have a suggestion for a roof/home improvement guy. Ours developed a leak this winter and after calling 8 places, only two called back. One called a day later. [Dave Koss](https://www.davekossvt.com/) is the one who called us back within the hour and came out within two hours. He had it fixed within 24 hours, and that includes the time to get shingles that matched the current ones. I don't know if he does fencing, but he might.”
Dave’s crew did a great job on a new deck in Hyde Park. Dave’s crew was neat and organized and left nothing behind other than a wonderful deck.
Dave Koss has done a lot of work for me in the past. I don't hesitate to call him back when in need because he and his crew are very experienced , hard workers out to make an honest dollar and not out to break your bank account. They do exellent, outstanding, professional work that you would indeed be happy with. Contact Dave and he gets right back to you unlike most construction companies.
I live in Shelburne Vermont. Dave replaced my 26 year old roof. he promptly came and gave a fair quote to do the project. Dave contacted me when he had a crew ready to do the roof replacement. Within days he had material shipped. When he reviewed the material delivery he noticed that the drip edge delivered was not what we had agreed on. He returned the material and brought back the correct product. The following day his crew came began the work, removing all shingles , paper, flashing and covered the entire roof with new paper and ice and water shield. They even started the new roof shingles and cleaned up most of the old material. the following day they finished the roof. I have spent my entire work career in the construction business but I have never seen a crew work so fast and efficiently in my life. During the construction the crew found where there was a leak around a roof vent. They replaced the plywood at no extra cost. Also my chimney vent came apart. Dave sent a crew over a week later and reinstalled the vent. I highly recommend Dave Koss Home Improvements. Great Guy and has a great crew. John A,
David Koss replaced the siding on my house (44squares) along with approximately 300 square feet of stone. Great job done, I am very pleased with their work and their congenital attitude.
David Koss and his crew did a fantastic job replacing old windows and a large sliding door, installing polyisocyanurate insulation and new siding plus handsome trim. His workers were consistently helpful, professional and thorough during the six weeks they were on the job. When they discovered some additional issues with the roof, David offered to fix the problem with no fuss and at minimal extra cost. When we were hit by a snowstorm, David turned up on a Sunday afternoon with his snowblower to help us clear the drive ready for Monday morning. David is a five-star gem and we unhesitatingly recommend Koss Home Improvement.
