“Excellent service throughout. Ashton came out to look at an issue raised on a part-exchange survey and, rather than recommend expensive remediation, told me honestly there was nothing wrong with the wall. Great to have an honest discussion.”

Why Dorchester homes get damp
Old and new homes in Dorchester get damp for different reasons. These are the ones we find most.
Cold, solid period walls
Victorian homes in Dorchester often have cold, solid walls that collect condensation and feel damp even when no water is getting in.
Wet ground near the Frome
Lower-lying homes towards the river and water meadows face higher ground moisture, which old damp proof courses cannot always hold back.
Wrong materials on old buildings
Cement pointing and impermeable paints on brick, flint and stone trap moisture inside the wall, so it comes out on the inside instead.
Condensation in newer homes
Airtight modern homes in Poundbury and Charlton Down can get mould if extractor fans and trickle ventilation are not doing their job.

Your local damp, mould & timber team in Dorchester
Dorchester is Dorset's county town, and its older streets are full of Georgian and Victorian homes built in brick, flint and stone with solid walls. Fordington, on the slope down to the River Frome and its water meadows, has some of the oldest housing, while the town centre has many listed and conservation-area properties where breathable, like-for-like repairs matter. Poundbury and Charlton Down are much newer, and there the problems we see are usually condensation, ventilation and occasional defects rather than rising damp. Because these two very different types of home sit side by side, a proper diagnosis is essential, and every survey we carry out follows PCA guidance.
