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

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

Yes, crawl space insulation is worth it if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home. Though you’ll pay more to install insulation initially, the savings you get from installing insulation can help offset those initial costs over time.

Spray foam insulation can last up to 80 to 100 years, making your investment worthwhile over the long run. Closed-cell spray foam tends to have the highest durability. Open-cell foam is subject to moisture, which can lead to deterioration. Remember that some spray foams will damage plastic piping, so consult a pro if you have PVC or CPVC pipes.
