Farnham

Spray foam, loft insulation and damp in Farnham homes

Farnham is one of the best preserved Georgian towns in the south. Castle Street and West Street are lined with red brick frontages, and behind many of them sit much older timber framed buildings. Farnham Castle looks down over the town, much of the centre is a conservation area and a large share of its buildings are listed.

Old buildings like these need breathable materials. Lime mortar, soft brick and timber frames move moisture in and out, and modern cement render or plastic paints can trap it. When we look at damp in central Farnham we check what the walls are made of before suggesting anything, and we take extra care in lofts where old timbers have been repaired over the years.

Outside the centre, the town spread in the Victorian and Edwardian era into The Bourne and Weybourne, where tile hanging and Arts and Crafts detailing are common. Interwar and post-war semis fill much of Badshot Lea, Hale and Upper Hale, and GU10 takes in villages such as Wrecclesham, Rowledge and Tilford. The interwar and post-war homes are the easy wins for an insulation top-up and raised boarding.

The North Wey runs through the low part of town, and streets near it have flooded in very wet spells, so damp there needs proper diagnosis. Spray foam turns up in Farnham lofts too, and many lenders and surveyors are cautious about spray foam. We remove it by hand and provide a Certificate of Removal. Insulation is Knauf mineral wool to 300mm.

Questions we get in Farnham

Can you treat damp in a listed Georgian house in Farnham?

Yes, with care. Old brick and timber framed walls need to breathe, so we avoid sealing them in. We find the source first, often gutters, render or raised ground outside. Listed buildings can need consent, so check with Waverley Borough Council. Damp proofing carries a 25-year insurance-backed guarantee.

Which parts of Farnham do you cover?

All of GU9 and GU10 from our Sevenoaks office, including the town centre, The Bourne, Weybourne, Hale, Upper Hale, Badshot Lea, Wrecclesham, Rowledge and Tilford. Surveys for loft insulation and spray foam removal are free, and you get a written price before any work is agreed.

Will loft insulation harm old timbers in my Farnham cottage?

Not if it is done properly. We use breathable Knauf mineral wool, keep ventilation at the eaves clear and check the timbers as we work. Anything worrying, such as old beetle damage or a leak, is photographed and shown to you before we go further.

Is spray foam a problem when selling in Farnham?

It can be. Many lenders and surveyors are cautious about spray foam, because it hides the roof timbers and can trap moisture. We remove it by hand, clean the timbers and give you a Certificate of Removal and 10-year guarantee to show your buyer's surveyor.

I live near the Wey. Is my damp from flooding?

Sometimes, but not always. After a flood, walls can take months to dry, and treating them too early wastes money. Damp near the river can also come from drainage or ground levels. We check what is really going on and tell you plainly what will and will not help.

How much insulation does a Farnham semi need?

Current guidance is around 270mm. Many interwar and post-war semis in Hale, Upper Hale and Badshot Lea have much less, often flattened by stored boxes. We top up with Knauf mineral wool to 300mm, backed by a 10-year guarantee, and can raise the boarding to keep your storage.
