Catisfield questions
Is sand mastic in a coastal place like Catisfield any different?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. Walls facing the sea are generally the first to need attention.
Do you cover smaller places like Catisfield?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
Can sand mastic be painted?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Can you match the sealant colour?
Normally, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
Are you fully insured?
Yes. We are fully insured.
How long does the job take?
That depends on how much there is to do, but most jobs take a few hours per window, depending on the condition of the joints. We’ll tell you when we quote.
Sand mastic in Catisfield, done properly
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. Typical jobs include gaps where the frame meets the masonry and crumbling sand mastic round a window, on brick reveals, timber door frames and sash and case windows.
Houses in smaller places like Catisfield can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
Big or small, you get the same 12-month guarantee.

Why it’s worth doing now in Catisfield
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and finishes neatly against the masonry. In an older home around Catisfield, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Different surfaces, different methods
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. If your home is listed, ask your local planning authority about consent.
Timber door frames
Round a period front door, sand mastic gives the right look.
Catisfield homes and the weather
Catisfield is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Ranvilles Infant School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Fareham station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. Homes close to Church of St Peter include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Landlords, agents and businesses in Catisfield
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
