I have over 30 years experience in my trade, in business for over 20 of those years. Check are accepted. Time and material is available as well. 1099's accepted for tax purposes. I have insurance up to $1,000,000 for property damage. Lic # C-35480

"We needed some drywall work done and H Drywall was one of three companies I contacted for estimates. They were the middle bidder, but I was so impressed with Harry’s (the”H” in H Drywall) on-site visit and his comprehensive proposal that I decided to go with them. I was not disappointed because Harry keeps on top of things and is quick to reply to messages. A bonus was their online payment system which is really convenient and provided instant confirmation of a payment. What truly makes this company worthy of a 5-star rating though are its employees. John, the foreman, is easy to talk to and has so much experience in construction that he solved any problems or challenges that occurred. He always kept us informed of their progress and made sure we were happy with the work they were doing. The rest of the crew Stuart, Derek, Chris, and Evan were all friendly, courteous (always aware that we still lived in the home), and did excellent work. Drywall replacement is messy, but these guys covered everything including the floors and they vacumed daily. The drywall removal uncovered some additional work that needed to be done and H Drywall provided a reasonable estimate to fix the problem. We also had them paint the living room, dining room, and kitchen areas. Thank you Evan for helping us choose the right color! This company, and I mean the whole company, definitely deserves a 5-star rating."

Insulation questions, answered by experts

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.

If you have bubble wrap lying around the house and you don’t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

Yes, products made from renewable resources and with reduced chemical impacts.

If you’re a savvy DIYer around the house, own the basic tools, and have enough time on your hands, you can definitely install fiberglass insulation yourself. Doing the work yourself will certainly keep overall insulation costs down. However, if you’re not confident in your handy skills around the house, call in a professional.
