Loft insulation for Portsmouth homes affected by heat loss, draughts and condensation

We install, upgrade and replace loft insulation across Portsmouth, including Southsea, North End, Copnor, Fratton, Hilsea, Cosham and Portchester.

Portsmouth homes often deal with a mix of heat loss, draughts and condensation, particularly in older terraced properties and homes closer to the coast. In many cases, insulation has compacted over time or no longer meets current standards.

Our surveys focus on the full loft space, including insulation levels, airflow, access and condition. This ensures the right solution is installed for long term performance.

We are rated 5 / 5 - 'Excellent'

Highly recommended

An excellent upgrade to our bungalow loft insulation. Three men in loft over a day and a half removing 45 large bags of fibreglass and replacing with 300 ml of rock wool insulation.Very professional and clean working. Highly recommended.

Spot on

Very efficient about how the work was carried out; the original insulation removed a large area of boarded loft removed before overlaying the installation of the new insulation between joist. Finally ‘hoovered’ stairs and hallway. PS stairs were covered before commencement of work. Very pleased

We are very happy

Excellent service by Tom and Charlie, from quote (3 months ago) to completion today. (Our delay).
Good work in our loft, completed with care and clear information about what’s to be done and what has been done.

Tom and Charlie are good to work with, they get on with the job and take care of details as well.

They completed the work in less time than expected! We were all happy!

We were very impressed

We had Tom in to quote for insulating my dad's loft and he was very down to earth and thorough, the quote arrived quickly, was very reasonable and we settled on a date around 3 weeks later.

The quality of Toms workmanship was very good, the roof space is exactly as he said it would be and everything was disposed of correctly and left clean and tidy as if no one had even been in. We even received a folder with all the details in it upon completion. I would not hesitate to recommend Tom to anyone and we were very impressed with the service we received.

Exceptional

Tom and his team were nothing but exceptional. From his initial visit to quote, he was insightful and helpful in laying out the various insulation and installation options. In the end we requested, the removal of insulation, new insulation installed, boarded loft space and a larger loft hatch. He arrived on time, installed in his said time estimate and left each of the two days he was here with an immaculate home. There was no mess, whatsoever. He prepped beforehand each day laying down protective materials on carpets etc. Would recommend and use again.
