Insul Kings is a fully licensed and insured weatherization contractor specializing in weatherization work (adding insulation to home), energy audits, whole house air-sealing, and the installation of various types of insulation for both commercial and residential projects. We are a proud partner of Mass Save & NH Save and are rated in the top 5% of their contractor scoring.

"Insul-Kings is wonderful to work with. They called in the morning to narrow the arrival time, which is very considerate. Nate and his crew arrived on time and CRANKED like a well oiled machine. I have a 4' crawl space. You can barely crouch. No problem! That's why God invented knee pads. They foamed and installed the insulation like it was their own home. It was a work of art. and came out better than I imagined. They patiently indulged my "old man" inquisitiveness. The crew represented Insul-Kings very well. I highly recommend them. This was done through the Mass Save program. So the $2100 job only cost me about $500.00"

Owner operated general residential repair work . Interior and exterior. Carpentry and Woodworking. Siding, trim, molding, doors, windows, .... serving Bedford, Lexington, Concord, Acton, and other neighbor towns for over 25 years. Uses Subs for electrical and plumbing. No travel charge.

"After Fernando removed old flooring, he found hard-to-remove glue on the subfloor. He took time to carefully remove the old glue using a hot gun. Everything he did was done thoughtfully and meticulously. After new flooring was installed, he choose to return to improve one detail, so everything would be done perfectly. Fernando is honest and pleasure to deal with. I highly recommend him."

If it has to do with walls or ceilings - we do and do it well. From frame to finish. Check out our web site to see examples of our work : www.charliesdrywallandpainting.com Hear what our customers are saying and contact us to come and see you project.

"After dealing with many disappointing contractors/handymen, Charlie & Richard were a (shocking) breath of fresh air and worth every penny. This company takes pride in their work and these two men truly want to do the best job for their customers in the long run. They do not cut corners at all and have extreme attention to detail. From the beginning, Charlie was organized, responsive and detailed in his quote. Over the course of 2 weeks, Richard and Charlie were consistently punctual and took great care to be respectful of our home (always used drop cloths everywhere they walked, swept/cleaned up after themselves daily & used the proper machines/filters so dust wouldn’t end up all over our house). The painting and drywall repair came out beautiful! I only wish I found this company sooner, but we will definitely be hiring Charlie & Richard again!"

You know all those odd jobs you could probably do yourself, but can't seem to find the time? We can help! No need to procrastinate, just give us a call and we'll have that project that has been hanging over your head done when you get home from work. In 1991 Bruce caught the "remodeling bug" when he purchased his 120 year old home in need of love and attention. He realized that he enjoyed the challenge of making something "old" become new again. Bruce spent 30 years as an industrial, graphic designer and excellent problem solver and diversified knowledge of building materials, process and repairs. Bruce began to see a need for busy homeowners. They needed to have someone dependable to do all those jobs around the home that just somehow never get done. He envisioned a "handyman" type of service that would show up on time, do quality work and charge a fair price. This is how "Thank You Handyman" came to life. Bruce's dedication to customer satisfaction and commitment to excellence! SEE WEBSITE FOR ADDITIONAL SERVICES OFFERED. www.thank-you-handyman.com

I offer free estimates that include a full description of the work discussed, as well as a cost breakdown and how payment is arranged. I accept cash, check, and money orders.

"Rick was fantastic! He worked around my schedule, made sure he had all the right materials, and did outstanding work at a very fair price. He also took great care to clean up afterwards and leave everywhere he worked looking just like he found it. He even took care of a couple other small “to-dos” unrelated to the job, which was a huge time and money saver! I wouldn’t hesitate to recommend Rick to anyone and everyone, and I know I’ll 100% use him again for future projects. Thank you!"

Insulation questions, answered by experts

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

The cost of installing spray foam insulation is $2,760 on average, but this cost can be as low as $650 or as high as $7,700. The main cost factor is the size of the insulated area and the type of spray foam insulation. 

Polyurethane spray foam costs between $0.44 and $1.50 per board foot, where a board foot is equal to the volume of a one-foot length of a board. More expensive options, like soybean or vegetable oil spray foam, range from $1.50 to $3.00 per board foot.

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.
