Dabella did windows and a shower in my home. Their salesperson Heather Hanson is very good at explaining the process and helpful afterwards with any help i needed. I'm very happy with the quality of the product and the craftsmanship on the installation.

Doorbell Installation questions, answered by experts

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

For your safety, you should always wear a mask when cutting batts of fiberglass insulation. We also recommend wearing eye protection, safety gloves, and long sleeves to protect your skin. Properly suiting up helps you avoid several fiberglass issues, such as cuts from the tiny shards of glass and inhaling small bits of fiberglass.
