Highlights
"Sealsixty did an excellent job of insulating our loft and installing a storage area above the insulation. They bagged and cleared all the old, filthy material and also lined the roof at a very competitive price. I have no hesitation in recommending them to prospective customers."
"Very happy with the service received. On visiting my house to discuss and survey what would be required to help with condensation, I was advised to have trickle vents, and a fan installed in the bathroom. This worked really well and eliminated any damp patches on the ceilings. Later down the line I had new fascias put in by a different company, which must have dislodged the loft insulation, so Sealsixty came and surveyed again and recommended fitting eaves trays and repaired and tidied the loft mineral wool. Hopefully this will stop any more problems. Thank you, highly recommend."

Smart checks
Before you hire a roofer
Never agree to roof work from a cold-caller at your door or an unsolicited 'we noticed your roof' note — that is the classic roofing scam.
Get a written quote that itemises access (scaffolding or a tower), the exact materials, and the workmanship guarantee — not a vague day rate.
Be wary of demands for a large cash deposit; agree staged payments against work you can actually see completed.
Look for consistent reviews across several named sources, not one polished profile.
Check any verified credentials, and that the business details independently check out.
