Spray foam is not always a problem. Ask for an inspection by a surveyor on the PCA's register of trained spray foam assessors, who has no interest in selling removal. More about spray foam removal.

Questions about spray foam removal in Porthmadog

How soon can you visit a home in Porthmadog?

We call you back to agree a time that suits you, and confirm the date in writing. Availability changes week to week, so we will give you the earliest slot we have.

Clear a path to the hatch and, if you can, move stored items away from the area we will be working in. Tell us about anything heavy or fragile.

Will I get a written quote for work in Porthmadog?

Yes. Every quote is in writing with the work, the price and what is included, so you can compare it properly.

Does spray foam always have to be removed?

No. It depends on the type of foam, how it was installed and the condition of the roof. An independent inspection is the only sound basis for the decision.

Will removing spray foam damage my roof?

Careless removal can tear the underlay or loosen tiles. We remove it by hand from inside and photograph the result so any damage found is recorded.
