Salisbury
Spray foam, loft insulation and damp in Salisbury homes
Salisbury is one of England's best preserved medieval cities. The centre is laid out on the old chequers grid, with timber-framed houses, Georgian brick fronts and flint and stone walls, and the Cathedral Close is lined with listed houses. Much of the city centre is a conservation area, so work in these homes has to respect old materials and the way they handle moisture.
Water is the other big factor. Salisbury sits where the Avon, Nadder, Bourne and Wylye meet, with the Ebble joining the Avon a little downstream, and the water table is high in low-lying parts of the city. Older homes near the rivers in Fisherton, Harnham and the city centre can suffer from rising and penetrating damp. We look for the cause before suggesting any treatment.
Beyond the centre, Salisbury has Victorian and Edwardian terraces off the Wilton Road and Devizes Road, post-war housing at Bemerton Heath, and newer estates at Bishopdown and Old Sarum. These homes tend to have accessible lofts where insulation has been squashed by storage or never brought up to today's levels, and a proper top-up with raised boarding makes a real difference.
Spray foam is often sold as a quick roof fix, but in a timber-framed or clay-tiled roof it can trap moisture against old timbers and hide decay. Many lenders and surveyors are cautious about spray foam. We remove it by hand, clean the timbers back and leave you photos and paperwork. For insulation we use breathable mineral wool, which suits old buildings and new ones alike.

Questions we get in Salisbury
Do you cover Salisbury and the surrounding villages?
Yes. We cover Salisbury across SP1, SP2, SP4 and SP5, from the city centre and Harnham out to Bemerton Heath, Laverstock, Old Sarum and Amesbury, plus Wilton and the Avon valley villages. Surveys for spray foam removal and loft insulation are free, and you get a written price before any work is agreed.
Why do older Salisbury homes near the rivers get damp?
Salisbury sits where four rivers meet, and the water table is high in low-lying parts of the city. Older homes with solid walls can draw moisture up from the ground, and blocked gutters or cement render make it worse. We trace the source first, then fix the outside as well as the inside.
Can you work on a listed house in the Cathedral Close or city centre?
Often, yes. Loft insulation and spray foam removal happen inside the roof and do not change how the house looks. Listed homes may still need listed building consent, so check with Wiltshire Council's planning team first. We use breathable materials that suit timber frames, flint and old brick, and flag anything we spot at the survey.
Is spray foam a problem in an old Salisbury roof?
It can be. In a timber-framed or clay-tiled roof, foam can trap moisture against old timbers and hide rot. Many lenders and surveyors are cautious about spray foam, so it often comes up when you sell or remortgage. We remove it by hand, clean the timbers back and give you photos and paperwork for your surveyor.
How much loft insulation should a Salisbury home have?
Current guidance is around 270mm of mineral wool. Many lofts have far less, or insulation squashed flat by boxes and boards laid straight on top. We clear old material where needed, lay new insulation to 270mm to 300mm and fit raised boarding so you can still store things up there without losing the heat.
What happens at a free survey in Salisbury?
We check the loft, the roof timbers, any spray foam and any damp walls, take photos and explain what we find in plain English. Then you get a written price, with no pressure and no obligation. If nothing needs doing, we will tell you that too. Surveys for spray foam removal and loft insulation are free.
