Professional loft insulation contractors

We install and replace loft insulation throughout Winchester, including Fulflood, Hyde, St Cross, Stanmore, Weeke, Harestock, Badger Farm and Oliver's Battery, as well as nearby Kings Worthy, Twyford, Alresford and Otterbourne.

Winchester has a high proportion of older and period homes, from Georgian and Victorian houses in and around the city centre to Victorian terraces in Fulflood and Hyde, alongside interwar and post-war homes in areas such as Stanmore, Weeke and Harestock and newer developments on the edge of the city. Older roofs often have no breathable membrane and rely on natural airflow, and some ceilings are fragile lath and plaster, so insulation needs to be installed carefully and without blocking ventilation. Our guide to loft insulation for period properties explains what to consider.

Our free survey checks the condition of your existing insulation, the ventilation and the roof space before we recommend a top-up or full replacement. Many owners of older homes choose breathable sheep's wool loft insulation, and you can find more about our standard service on the main loft insulation page. We also provide loft boarding in Winchester and spray foam removal in Winchester.

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.
