“Excellent service from start to finish. The survey was thorough and professional, with honest, evidence-based advice rather than trying to sell unnecessary work. I came away with complete peace of mind.”

“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.”

Areas we cover near Bournemouth
Our specialists regularly work throughout Bournemouth and the surrounding neighbourhoods.
Below-ground damp in Bournemouth
Bournemouth’s hilly chines and large Victorian villas mean many homes have cellars, lower ground floors or walls built into the slope.
Cellars in Victorian villas
Larger villas in Westbourne, Talbot Woods and Boscombe often have cellars that were never designed to be dry living space.
Retaining walls on slopes
Homes built into the hillside have rooms against earth-retaining walls, where water pressure drives moisture straight through the masonry.
Lower ground floor flats
Converted lower ground floors suffer lateral damp through the walls and floor, causing mould, salts and failing plaster.
How we waterproof basements in Bournemouth
1. Waterproofing survey
We assess the ground, water pressure, drainage and intended use of the space to design a system in line with BS 8102.
2. Install the system
Barrier tanking or a maintainable cavity drain membrane — our Proofterior Dry System — with sumps and drainage where required.
3. Finish the space
Specialist replastering or dry-lining leaves a permanently dry, decoratable room ready for use.
