What exactly is cavity wall insulation and why do I need it?

Cavity wall insulation involves filling the gap between the inner and outer layers of your external walls with material that reduces heat loss. This type of insulation is essential for maintaining a comfortable indoor temperature, lowering heating costs, and reducing carbon emissions. If your home has unfilled cavity walls, you are likely losing heat and thus spending more on energy bills.

How do I know if my cavity wall insulation needs to be removed or replaced?

Signs that your insulation may need attention include dampness on interior walls, mold growth, and unusually high heating costs. These issues can arise from insulation being old, damaged, or improperly installed. It’s best to have your walls assessed by professionals like us to determine whether the insulation needs removal and replacement.

What are the risks of not replacing failed wall ties?

Wall ties are crucial for stability, holding the two layers of a cavity wall together. If these ties fail, it can lead to significant structural damage, such as bulging or collapsing walls. Replacing failed wall ties promptly prevents further damage and maintains the integrity and safety of your building.

What materials do you use for cavity wall insulation?

We primarily use materials like mineral wool, polystyrene beads, and foam insulants, depending on the best fit for your property and specific insulation requirements. All materials we use are industry-approved for safety and efficiency.

Can cavity wall insulation cause damp?

If improperly installed, cavity wall insulation can trap moisture and lead to damp issues. However, with professional installation by accredited installers like Cavitech, the risk is minimized. Our team ensures that all installations are performed correctly and conditions are suitable for cavity wall insulation to prevent any damp problems.

How long does it take to install cavity wall insulation?

The installation typically takes about half a day for an average-sized house, but this can vary based on the size and condition of the property. We strive to ensure minimal disruption and complete the process as efficiently as possible.

What guarantees do you offer with your insulation services?

We provide a guarantee on all our insulation services, which covers the quality of workmanship and the materials used. This guarantee typically lasts for 25 years, giving you peace of mind that your insulation investment is protected.

What Our Customers Have To Say About Cavitech

COMPANIES WE HAVE WORKED WITH:

My initial contact with Cavitech was with Joshua who advised me it was a good idea to have the free test done by their building engineer who advised me that I did have the old type of insulation. He spoke to me a couple of times regarding my house and options to have it refilled with the new type of cavity wall insulation. I then decided from the wrote what I wanted done and the chap turned up on time and did an excellent job removing all the insulation. He explained to me how the process works and it was done in a few hours and he cleared up after very well.

Very efficient. Got the job done within one week of the quote. Noticed instantly how much warmer the house was.

Job was completed in a short period of time and was done to a very high standard. The left everything really tidy, you wouldn’t have known they’d been.

My husband called Cavitech to ask for a quote. It only took Josh 10 minutes to email the quote through! It was much more reasonably priced in comparison to another quote we had received to extract a fraction of the amount of insulation. Josh was very helpful and responded very quickly to further queries. Neil, who carried out the work was brilliant! Friendly, efficient, took time to explain every step of the process as he was doing it. Will definitely recommend this company. Fantastic from start to finish!
