Lunsford's Cross: your questions answered
Does the coastal weather in Lunsford's Cross affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Will you come out to Lunsford's Cross?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We check where the draught is before we start.
Can I paint over the new sealant?
Not generally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
What should I tell you?
A short description and the location. If we need more, we will ask.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months.
Window mastic in Lunsford's Cross
From a single sill to a whole house of windows, the work is priced before anything is done. Just phone 0345 464 0079 or email us and tell us how many frames there are and how they’re reached. If you have leaking joints at the ends of sills and mastic that’s falling out in pieces, we can put it right.
Homes in small places like Lunsford's Cross often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Each job carries a 12-month guarantee, large or small.

The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a morning for a couple of windows and a door. For a village or hamlet like Lunsford's Cross, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Tell us if parking is tricky
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints

What the job involves on each surface
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.
Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Landlords, agents and businesses in Lunsford's Cross
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Frames and glazing around Lunsford's Cross
Lunsford's Cross is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Collington station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Ninfield Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What happens if it’s left?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Lunsford's Cross, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.
