Unit 1 & 2, Grantham, NG31 9ST
A family-run remedial construction business spanning three generations. Built on honest diagnosis, quality craftsmanship, and a genuine commitment to getting things right across the East Midlands.
Dower Damp Proofing was founded in 1972 with a straightforward philosophy: understand the problem before you try to fix it. Back then, that approach set the business apart. Too many companies in the damp proofing industry were selling treatments first and asking questions later. Dower took a different path, starting every job with a thorough diagnosis and building a reputation on honest, evidence-based advice.
Three generations later, that philosophy has not changed. The tools and techniques have evolved, but the principle remains the same. Every survey starts with understanding the property, the construction, the environment, and the actual source of moisture. Only then is a specification put together. It is a slower approach than some, but it is the right one, and it is why the vast majority of our work still comes through recommendation and repeat custom.
Approaching 4,000 successfully completed projects across the East Midlands, every single one backed by a written guarantee, we have built a track record that speaks for itself. We are not a franchise and we are not a national call centre. We are a hands-on family business that still believes the best way to build trust is to do good work, stand behind it, and let the results do the talking.
The principles that have guided our business for over 50 years. They are not just words on a page. They shape every survey, every specification, and every installation we carry out.
We never recommend unnecessary work. Every job starts with understanding the actual problem, not selling a product or treatment. If your property does not need remedial work, we will tell you.
Unlike larger nationwide companies, we design every specification around what your building actually needs. No one-size-fits-all treatments. No off-the-shelf packages. Just the right solution for your property.
Our work is carried out by trained operatives, not subcontractors. We use quality materials, follow British Standards, and take pride in doing things properly the first time. No shortcuts, no substitutions.
Every piece of work we carry out is backed by a comprehensive 20-year guarantee. With over 4,000 guarantees issued and counting, we stand behind our work because we are confident in how it is done.
The story of Dower Damp Proofing starts in 1972, in Lincolnshire. The business was founded on a simple belief: that proper remedial construction work begins with understanding the building, not reaching for the nearest treatment. That meant investing time in thorough surveys, writing clear specifications, and carrying out work to a standard that would last. It was not the fastest way to grow a business, but it was the honest way.
The second generation brought new capabilities and expanded the service area across the East Midlands. The company added timber treatment, heritage restoration, and insurance reinstatement to its offering, all built on the same diagnostic-first approach. The third generation has continued to build on that foundation, combining modern building science and contemporary techniques with the traditional values the business was founded on.
Today, Dower Group handles everything from stately homes and Grade II listed properties to Victorian terraces, post-war housing, and modern developments. The common thread across every project, regardless of scale or complexity, is the same commitment to honest assessment, quality delivery, and a guarantee that actually means something.
Over 50 years in the industry means we have built strong working relationships with a wide range of professionals. Architects and structural engineers trust us for specialist remedial input on complex projects. Estate and letting agents rely on our honest assessments and clear reporting when buying, selling, or managing properties. Local councils and housing associations use our services for social housing stock and public buildings where damp and timber issues need resolving quickly and properly.
Private homeowners make up a large part of our work, and we treat every home with the same level of care and professionalism whether it is a two-bedroom terrace or a six-bedroom country house. We explain what we find in plain English, outline exactly what needs doing and why, and provide a fully itemised quotation so there are no surprises.
Our project history covers listed buildings, historic conversions, Georgian townhouses, Victorian terraces, Edwardian semis, post-war housing, barn conversions, commercial premises, churches, and modern new-builds. The range of property types across the East Midlands demands versatility, and that is exactly what three generations of hands-on experience delivers.
A closer look at our story, our craft, and the approach that has guided three generations of remedial work across the East Midlands.
Whether you need a specialist survey, a second opinion, or just some honest advice about a damp issue, get in touch. We have been helping property owners across the East Midlands for over 50 years and we are always happy to talk.
Look for a damp specialist who surveys before quoting, explains which type of damp you actually have, and gives a written report and a fixed price rather than a vague estimate. A long-term guarantee and clear local references matter too. We always diagnose first, put everything in writing, and stand behind our remedial damp proofing with a 20 year guarantee across the East Midlands.
