Cavity wall insulation for landlords in Bangor, County Down: questions

How soon can you visit in Bangor?

We arrange dates when you get in touch. Availability varies through the year, so we give you real dates rather than a promise on the website.

Which building regulations route applies in Bangor?

Bangor is in Northern Ireland, so inserting cavity wall insulation needs a building control application to the council before work starts. We confirm the route in writing on your quote.

Is the survey free in Bangor?

Yes when it is for an install quote. Standalone reports for Bangor buyers, sellers or landlords who do not need an install quote are priced before you book.

Is my Bangor home too exposed for cavity insulation?

Parts of County Down get some of the heaviest wind-driven rain in the UK, so the survey is stricter and some walls are better left unfilled. The survey records the exposure of each wall before recommending a material, or recommending against filling.
