Weymouth
Spray foam, loft insulation and damp in Weymouth homes
Weymouth became a fashionable resort in the late 18th century after George III began holidaying here, and the Georgian terraces along the Esplanade date from that time. Many are listed and the seafront sits in a conservation area. Most of those terraces are now flats or guest houses, with solid brick or stone walls, rendered fronts and shallow roofs behind parapets.
Melcombe Regis, the strip between the harbour, Radipole Lake and the beach, is low and flat. Ground floors and basements there can hold damp, and a high water table makes it worse in wet winters. Add salt air and south-westerly gales off the bay, and seafront walls take a battering. We check render, pointing, parapet gutters and ground levels before recommending any damp proofing.
Behind the seafront the town is more varied. Rodwell and the streets around the harbour have Victorian terraces, Westham and Wyke Regis mix Victorian, Edwardian and interwar homes, and Littlemoor, Preston and Chickerell have larger post-war and later estates. Portland, across the causeway, is built from its own famous stone and is one of the most exposed places on the south coast.
For loft work, the interwar and post-war homes are where we usually help most: thin, squashed insulation topped up to 300mm of Knauf mineral wool, with raised boarding for storage. Spray foam turns up too, sometimes sprayed under old roofs to stop wind-driven draughts. Many lenders and surveyors are cautious about spray foam, so we remove it by hand and clean the timbers back.

Questions we get in Weymouth
Do you cover Portland as well as Weymouth?
Yes. We cover Weymouth across DT3 and DT4, including Melcombe Regis, Rodwell, Westham, Wyke Regis, Preston, Littlemoor and Chickerell, and Portland in DT5. Surveys for spray foam removal and loft insulation are free, and you get a written price before any work is agreed.
Why are seafront flats in Weymouth so often damp?
The Georgian terraces face the full force of south-westerly gales and salt air, which wear down render, pointing and parapet gutters. Water gets in high up and shows inside. Low ground in Melcombe Regis adds rising damp to the mix. We find the real cause before suggesting any work.
Can you treat damp in a Weymouth basement?
Often, yes. Basements in Melcombe Regis sit on low ground with a high water table. We look at drainage and ground levels first, then recommend the right treatment for the wall. Damp proofing work comes with a 25-year insurance-backed guarantee, set out in your written price.
Can you insulate a listed building in Weymouth?
Often, yes. Loft insulation goes inside the roof and does not change how the building looks, but listed homes may need consent, so check with Dorset Council first. We use breathable mineral wool that suits old brick, stone and timber, and flag anything we spot at the survey.
How much loft insulation does my Weymouth home need?
Current guidance is around 270mm. Many interwar and post-war homes in Westham, Preston and Littlemoor have much less. We lay Knauf mineral wool to 300mm with a 10-year guarantee, and fit raised boarding so you can still store things without squashing the insulation.
Is spray foam a problem in exposed coastal homes?
It can be. Spray foam is sometimes added to stop draughts in windy spots, but it hides the timbers and can trap moisture against them. Many lenders and surveyors are cautious about spray foam. We remove it by hand, clean the timbers back and give you a Certificate of Removal.
