Customers say: Quick response

"Really excellent work insulating an old house with dormers and limited headroom. The attic living space is noticeably improved by the insulation and the rest of the house maintains a more constant temperature. The workers were pleasant, the folks I was in touch with from the office were communicative. Overall, I would recommend Brittin Built for this kind of project."

"I RECENTLY HAD MY ATTIC INSULATION REPLACED BY MASTER ATTIC. ALEX CAME OUT RIGHT ON SCHEDULE AND GAVE ME A FAIR PRICE. ( I DID HAVE 4 OTHER ESTIMATES) THE CREW LEAD BY ROBERTO WAS AMAZING. THEY WERE VERY CONSIDERATE, CAREFUL IN MAKING SURE THE AREA WAS SEALED OFF AND WERE VERY CAREFUL OF MY PERSONAL BELONGINGS. THEY DID A GREAT JOB IN REMOVING OLD INSULATION , VACUUMING OUT THE ATTIC ,SPRAYED AREA AND SEALED ANY OPENINGS. BEFORE THEY BROUGHT IN NEW INSULATION, THEY ASKED ME IF I WISHED TO TO VIEW THE ATTIC AND I DID. I WAS AMAZED EVEN AT THIS POINT, HOW CLEANED EVERYTHING LOOKED . (THIS INSULATION HAD BEEN UP THERE FOR 70 YEARS) NEW INSULATION WAS INSTALLED AND IT LOOKS GREAT. THE CREWED CLEANED UP EVERYTHING , EVEN VACUUMED THE AREA IN THE ROOM. ALL BAGS OF OLD INSULATION WERE REMOVED PROMPTLY AND I WOULD HIGHLY RECOMMEND THEM TO ANYONE."

"Angel installed a new vinyl floor, cabinet, and sink in my laundry room. Also replaced an interior door, and did troubleshooting on a leak we were having in our sunroom. Angel stayed in touch throughout the process, arrived on time and did flawless work, we couldn’t be more pleased. Would highly recommend for any home improvement projects you may have."

"Score Construction performed a full demolition and renovation of my bathroom, as well as an update of my electrical panel from fuse to circuit breakers. The outcome of the bathroom project is beautiful and modern. The team worked daily and finished the work within the projected schedule. The pricing was reasonable and clear. The contractor/owner of Score was alwlays responsive to all of my needs and questions. I appreciated working with Score as they are honest and thorough."

"I was seeking a significant augmentation of insulation in my attic, since the existing insulation was 31 years old, and had become very thin, and shoved around over several decades of work up there. After vetting 4 contractors, I chose Western Pest Services, and was very pleased with the entire process. they did a thorough evaluation of the attic space, evaluated my plan to run the installation tube through a 2nd floor window, and confirmed that there are no pests in the space. I felt that the price was fair - and the technicians did a terrific job in less time than I had expected. Definitely recommend them!"

"Wow... just wow. I feel like the clock rolled back several years to the days when tradesmen where available, on time, skilled and affordable. Koala is a rare find. These guys have it all together. Sal is the sparkplug that makes it work seamlessly. He guides you in just what you need, and nothing you don't need. His estimates are detailed and very fair pricing. After consulting with Sal he was able to schedule the work in less than a week. The installation crew called ahead on the scheduled day and arrived exactly on time. Shawn led the crew of 4 techs who worked neatly and thoroughly, and cleaned up well. They did rim joist sealing and batt insulation in a somewhat complex situation where I have I joists adjoining the band board. They also did blown in fiberglass in the attic. For anyone considering insulation of any format I highly recommend Sal and Koala. And, the best part of this experience with the company....the total cost less than others who had rebate programs."

"Unfortunately, when the techs started the process, the insulation already in the walls prohibited the addition of the foam. I cannot begin to tell you how disappointed I was, as the job they had done on our tiny addition was remarkable. However, isn't it wonderful to have a company tell you the truth!"

Insulation questions, answered by experts

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

The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

You can buy pipe insulation materials in your local hardware store or in major home improvement stores. You can also shop for insulation online, where you may be able to more easily buy in bulk. When shopping, make sure you know your pipe's dimensions so you can buy the correct size of pipe insulation materials for your pipes.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.
