Why you should install or replace your home's insulation?

Here at Northwest Crawl Space Services, we find that the most common reason is animal damage to the insulation.

Rats, mice, raccoons, and possums are common animals in our state. They like to use insulation to warm up and nest in it, causing significant damage and filling it with bacteria. This can happen in your attic, crawl space, or even inside your walls.

Air Seal for Your Home

To maximize the energy efficiency of the insulation project, gaps that leak air must be eliminated before the new insulation is installed. Northwest Crawl Space Services performs an air seal service as part of every attic or crawl space insulation project.

In this service, we look for any penetrations in the ceiling or floor where plumbing, ducting, or electrical goes through and seal them to prevent air leaks.

If you notice high energy bills, difficulty keeping your house warm or cool, rodents in crawl spaces, or believe your insulation needs to be updated, call Northwest Crawl Space Services. 

Our experts will perform a full inspection and provide an energy-efficient solution that is perfect for your home!

Our Reviews

We recently hired Northwest Crawl Space Services to perform a complete remediation of our crawl space which had a rodent infestation. Lior initially came out and did a thorough assessment and explanation of what work needed to be done. He was very detailed in explaining all work that they would do and the subsequent follow up visits and warranty that was included in the price. The following week Robert and his crew came out to perform the work. They were punctual, courteous and extremely professional in every way. They took caution and care to make sure that the inside of our house was properly masked off and protected as they removed the entirety of the contaminated crawl space insulation etc. Robert provided me with detailed pictures of the finished work and as well as pictures of a couple water pipes that had very small leaks, which I greatly appreciated. As promised, Lior came back out two weeks later to inspect all work and make sure that there were no problems. I highly recommend Northwest Crawl Space Services!

Lior and his team were fantastic. They were cheaper than the big name companies and didn't try to upsell me to repairs that didn't need to be done. They took care of the problem quickly and were great with communication and photos of the project as it was being completed. They owner even did a follow up the next day to make sure the job was done correctly. I had a list of questions when the job was done and he already had them all addressed with pictures and videos of everything. They are locally owned and operated which is very important to me. Would highly recommend

NW Crawlspace is an exceptional company. Matan and his team are experts at repairing Crawlspaces and protecting you from rodent and water Intrusion.. Rob and Leonardo and the team take the quality of their work personally. They are going to do it right and come back to check it for you. We needed a total clean out and sump pump system installed.They worked super hard to have it done by Thanksgiving. We feel like we got a bargain after seeing all that was done. I recommend them if you want your crawlspace worked on or inspected. You will be glad you called them.

We had a sump pump fail and ended up with a crawlspace that had at least two feet of standing water. Matan of Northwest Crawlspace Services came out to inspect. After examination, he carefully explained our problem and his proposed solution using easy-to-understand, non-technical language, and then gave us a firm price quote. His professionalism made us feel very much at ease and gave us assurance that we were in good hands. The very next day, a worker was sent to pump the water out of the crawlspace so that work could begin. After the water was gone, a crew of three workers was dispatched to begin the work. Before doing anything, they took great care to install plastic sheeting to protect all of the walls and floors leading up to the crawl space access door. The crew worked diligently throughout the day and completed most of the work. Afterwards, they thoroughly cleaned up, leaving little sign that they had even been there. The following day, they came back to finish the work and replace some duct work that had been damaged by the flooding. A little later, a separate person (presumably a supervisor) came by to inspect the job. We are thoroughly satisfied by the work of Northwest Crawlspace Services and would highly recommend them to other homeowners.

Frequently asked questions

What does R-value mean in insulation?

The R-value measures the thermal resistance of insulation material. It indicates how effectively the insulation resists heat flow, with higher R-values signifying better insulation performance and greater resistance to heat transfer.

No, in cases of older homes that were built under old codes, some of the structures may not allow enough depth to accommodate the thickness of insulation required according to today’s standard codes.

Insulation services can increase the resale value of your home by making it more energy-efficient, comfortable, and attractive to potential buyers. Well-insulated homes typically command higher resale values due to lower utility costs and improved overall comfort and livability.

We offer a variety of insulation materials, including fiberglass, cellulose, mineral wool, and foam sleeves insulation. Our selection is based on factors such as energy efficiency, durability, environmental impact, budget and specific requirements of your home. We assess your insulation needs and recommend the most suitable material accordingly.

Signs that your home may need insulation services include uneven indoor temperatures, high energy bills, drafts, moisture issues, and excessive noise transfer. Our team can conduct a thorough assessment of your home to determine its insulation needs and recommend appropriate solutions to improve energy efficiency and comfort.

Blow-in insulation and batt insulation are two common types of insulation used in buildings, each with its own set of advantages and applications.

Blow-in insulation, also known as loose-fill insulation, consists of small particles of fiber, foam, or other materials. It is applied using a blowing machine, making it ideal for insulating areas with irregular shapes or hard-to-reach spaces such as attics or walls with obstructions. This method provides better coverage in difficult-to-access areas and can be more effective at reducing air leakage.

On the other hand, batt insulation is composed of pre-cut panels or rolls made from materials like fiberglass or rock wool. These panels are installed by fitting them between studs, joists, or rafters. Batt insulation is more straightforward to install and is commonly used in standard wall cavities and attics with ample space.

Ultimately, the choice between blow-in and batt insulation depends on factors such as the specific requirements of the project, the structure of the building, and budget considerations. Both types of insulation have their advantages and are suitable for different applications.
