Can You Sell a House with Spray Foam Insulation?

Selling a house with spray foam insulation can raise survey and mortgage concerns. Learn what UK homeowners should check and how EvoHome can help. Many UK homeowners with spray foam insulation are surprised when they try to sell. Buyers, surveyors and lenders may raise concerns, sales can be delayed, and the situation can feel overwhelming.

The good news: many homes with spray foam are still sold every week. The key is understanding the issue calmly before making any major decisions. ## Why spray foam can affect a sale Spray foam in a loft – particularly when applied to the underside of the roof – can make it harder for surveyors to inspect roof timbers.

That single point creates most of the concerns buyers and lenders raise. It is rarely about the foam itself and usually about the *evidence* available about the roof beneath it. ## Why buyers and lenders may be cautious Different lenders take different views. Some accept spray foam in certain conditions; others ask for evidence, specialist reports or removal.

Buyers reading negative news coverage may feel cautious even if their lender would lend. ## What surveyors may look for - Whether roof timbers can be inspected - Ventilation and moisture risk - Foam type (open-cell vs closed-cell) - Quality and continuity of installation - Any visible damp, condensation or staining - Original installer paperwork and guarantees ## What paperwork may help Original installer documentation, product datasheets, guarantee certificates and any independent inspection reports can all help.

If you do not have them, EvoHome can advise what to gather. ## Whether removal may be needed Removal is sometimes the right answer – but not always. In many cases an inspection report or specialist assessment is enough to satisfy a lender. Removing spray foam unnecessarily is expensive and not without risk. ## Why removal is not always the first step Be wary of any company that recommends removal before properly understanding your property, your foam type and the specific reason your sale has stalled.

## What to do if your sale is delayed 1. Keep calm and gather the facts 2. Ask the buyer's surveyor or lender exactly what they need 3. Send EvoHome Improvements photos, measurements and survey comments for remote review 4. Decide your next step based on evidence, not pressure ## Want us to review your spray foam issue remotely?
