"** This review is posted on behalf of my friend who recently used their service ** I can't say enough good things about Rich, Conrad, and his entire crew. First and foremost, these guys are 100% professionals. Do not overlook professionalism. I received other quotes from people who were either unwilling to do the full spectrum of work requested or not thorough in the initial review. We recently moved into a 1920s home that had old and brittle insulation laid around knob-and-tube wiring. So not only was the attic insulation ineffective, it also presented itself as a fire hazard. To make matters worse, there was a relatively inaccessible portion of the attic (i.e. access through a child-sized square cutout) they'd have to work their way into. At the very day/time of the appointment, Rich had already gotten to the house early (let in by our floor guy) and already ventured up into that tiny crawl space in the attic to assess the work. He made all of his notes and took photos before I even realized he was there. Keep in mind, insulators from other companies did not even bother to poke their heads into that space. When I mentioned what our ideal timeline was, Rich said that if they couldn't fit the work into our schedule, they would refer us to other companies they trust. Needless to say, I was impressed by his honesty. After receiving a quote via email from Conrad - who is on top of everything with phone and email communications and reminders - we decided that they were worth the three weeks wait. I signed the quote and we agreed on a start date. Conrad sent a reminder email a few days before the work was to start. The guys came on time and worked all day to remove the old crumbled insulation. By the end of the day, they were covered in black fiber/soot. They found all types of things around the attic that we weren't aware of - head boards, window screens, lumber, etc. They even removed most of the junk for us. A week later (after we brought in the electricians to update the wiring), they came back to lay the insulation batts, apply the batts to the walls where stated, air seal openings, and create a seal for the attic crawl space access cutout). They were able to complete the job over the course of a full day (9am to 7pm). They are professional, honest, thorough, responsive (emails were always returned timely and in that one week away, Rich returned my call to answer an insulation question), always on time, fairly priced (better, even), and skilled. And on top of everything else, the whole crew was fun to talk to. I couldn't have asked for a better experience. I would recommend them as your #1 choice for your insulation needs."

"We had radiant barrier insulation installed insteads of blown in insulation. It was laid in the attic rafters, upon the completion of the job the service provider could have done a better job of cleaning up. He also left some marking on our cabinet. When the gentleman came over to give us an idea of what radiant barrier is we never knew when he would be there, they gave us an estimate but then upon completion we wrote a check, but never received a receipt of payment, or work order showing completed work. All we had was the gentleman sign the estimate that we had been given two weeks prior to the job. And the installer did not have any paperwork saying that he did the job. But we had him write that on the estimate. I would expect more professional paperwork."

"Excellent service From the first day, Manuel came to inspect my attic and gave me different options that fit my budget. They sealed all the rat entrances and disinfected them. The price was very reasonable. The crew was very careful with the walls of my house. They covered the floor with blankets. At the end of the day, they showed me photos of the entire process. I definitely recommend Ds Insulation."

FAQs for insulation service projects in Davis, CA

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.
