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

When it comes to window coverings, cellular shades are typically known as the most energy-efficient option. Cellular shades are also known as honeycomb shades. They are made of a soft fabric and take the form of “honeycomb” cells. These cell pockets trap air in and around your windows, providing insulation.

While carpet over carpet may provide some additional insulation and soundproofing benefits, it's not as effective as other methods. Layering carpets can add a modest buffer against noise and temperature fluctuations, but it's limited compared to installing thicker carpet padding or using specialized soundproofing materials. For optimal floor insulation and soundproofing, consider alternative solutions tailored to your specific needs and budget, such as adding additional padding or soundproofing underlayments beneath the carpet.

Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into spray foam insulation or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.

If you're replacing insulation, it's a good idea to remove the old insulation before adding new. This is especially true if the existing insulation has suffered from water damage or been exposed to pests. You also need to remove old insulation if you'll be installing a new and different type of insulation, such as trading roll or batt insulation for spray foam.

Spray foam insulation doesn’t do well around heat sources. Therefore, You can use spray foam insulation to seal around HVAC boots that penetrate through the drywalls or around where wrapped ducts connect to the boots, but we don’t recommend using spray foam insulation to encapsulate your air ducts. Spray foam insulation on air ducts is also less effective compared to duct wraps.
