"

I own a 1937 farmhouse in Whatcom County. I had concerns about the insulation in the crawl space and the attic. The owner of RGS came to my home and spent an hour inspecting the areas I was concerned about after which he sat down with me, explained what was needed and gave me a bid to do the work. The owner is as professional, knowledgeable and courteous as any business owner I have ever met. He quoted me a great price and gave me the highest quality of service I could have hoped for. I was so happy with RGS that I asked him to inspect the crawl spaces of two rental properties I own in Bellingham. I highly recommend that you ask RGS for to bid on any of your insulation needs. You will not be disappointed.

"I needed my attic insulation updated. It had the original “blown in” loose material from 1975. After 49 years it had deteriorated and compressed. It was only a few inches deep. Also a leak in our old roof (recently replaced) had caused some mold in the old insulation. It had to be removed completely and redone. I called JB Insulation and asked for an estimate. Jose came over and inspected our attic. His experience and expertise was evident by how he explained everything. I felt very confident that I wanted his company to do the job. His price was very competitive and offered us the most value for our money. On the day of the job, his guys took much care in preparing for the job. They covered and taped our floors and wall corners to protect our home’s interior. They used a high powered insulation vacuum and removed all of the old insulation. They installed the new insulation and new baffles all in one day. Our attic looks great and we are really happy with their work. Yes I would recommend JB Insulation."

"We were on a tight budget due to unforeseen costs from other parts of our lives. Rafael was very accommodating and helped guide us to the best option. We had our garage completely resided but could afford the whole house. They did one side of the house which was critical. The cost was within bid given and the work was amazingly fast, friendly and professional. We will use them again to finish the rest of the house once we are back financially."

"Terence came and looked at our crawlspace, and told us we had post and beam construction, and described what they could do to insulate. We got two estimates from them (and another from a different company). We hired Hybrid. The crew was pleasant, hard working, and cleaned up when they were done. The work took longer than they predicted by a day, and the estimate was probably too low. They honored it. We'd hire them again in a minute."

"Fantastic.Jon was amazing as a contractor, and his team of subs he brought in were also great. The work done was top notch and I'd be happy to refer him to anyone else (which I've done). Great experience for a big project involving plumbing, electrical, kitchen remodel, the beginning of my small bathroom remodel and opening up the doorway from my living room to the kitchen. He is such a great guy, and it made a very scary process for me much less scary."

Insulation questions, answered by experts

Insulation provides additional protection for your tankless water heater. Even if the unit is installed inside the house, it’s still a good idea to wrap the unit up with insulation batts, especially if you live in cold climates. For outdoor units, you can build an insulated box around the tankless water heater for freeze protection.

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

Bathroom wall insulation not only keeps the area temperate, but it also reduces instances of mold, mildew, and rot. Bathrooms, after all, are havens for moisture. With this in mind, it’s absolutely worth it to insulate bathroom walls since it saves money in the long run. You won’t have to hire a pricey mold remediation service down the line. Also, insulation decreases outdoor noise and lowers energy costs.

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.
