"The salesman that came to the house and gave the quote was professional and did not apply any pressure to buy. He listened to what I was looking to have completed and was able to give me a very competitive quote. I did acquire two more quotes but Seal Tech provided me not only the better quote but also the most comfortable. The installers showed up on time, took precaution to protect our landscaping and installed the foam insulation. We noticed that the application in the walls have left our home much more comfortable and over the past three months our utility usage has gone down at least 10% each month.

"Scott Dennison and his team at Dennison Exterior Solutions & Gutter Toppers have recently completed a roof replacement on our home. Some reasons for choosing them to do the work included: their emphasis on the importance of good ventilation for maintaining the integrity of the roof over time, that their installers are certified by the shingle manufacturer, and that the roof system comes with an impressive 50 year warranty, which stays with the house if the owner changes. We have some experience with roofing systems and during the initial meeting with them we were impressed by their knowledge, and the emphasis on roof modifications that would get the ventilation right. Other reviewers have described the process and attention to detail that was part of their experience with this company. Our experience was comparable and we are well-pleased with the exceptional experience we had with them. Luis and Patricia were the primary crew members on our job; we are grateful for their excellent work and their attention to the details. The quote from Dennison was a bit higher than others. However. the end product included a high quality installation, a competent and professional business relationship with their company and an excellent warranty. Altogether, the higher cost was more than justified for us. Without hesitation we would (and have) recommend this company to neighbors and friends."

"I paid $99 for a roofing inspection and maintenance plan. He did come out and inspect the roof but he did not do any maintenance. He indicated repairs were needed and provided a quote. So, I felt like I paid for a quote which most companies will do for free. The quote for repairs was significant. I questioned if it would be better to replace the roof and asked for a quote for that and he never got back to me.

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
