Window mastic in Priestwood Green, done properly
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. If you are dealing with untidy mastic left by window fitters and draughty joints inside around the window, we can help, whatever the surface.
Somewhere as small as Priestwood Green, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

Priestwood Green questions
Do you cover smaller places like Priestwood Green?
Yes, Priestwood Green is covered. Our work covers 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 you help a landlord with a rental near Sole Street station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
How long before the joint can be used?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Is the work guaranteed?
Yes. Every job comes with our one-year guarantee, and we are fully insured.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a morning for a couple of windows and a door, depending on the amount of work. In a small place like Priestwood Green, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
How to get a quote

Related advice
How the job changes by surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Avoid harsh chemicals near the mastic
- Keep drainage slots and sill grooves clear
- Paint up to the joint, not over it
- Clean frames with a soft cloth and soapy water
Keep the new mastic undisturbed while it cures, for as long as we advise. Keep jet washers away from the frames.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Do you need window mastic in Priestwood Green?
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
It’s worth asking for a quote if you see:
- Sealant in the wrong colour for the frame
- Hard, cracked sealant around windows
- Gaps left after new windows were fitted
- Damp patches on the reveal after heavy rain
For an older house near a landmark such as Church of Our Lady of the Meadow, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- How the colour is chosen
- What happens if they find a problem under the old sealant
- What the quote includes, VAT included or not
- How long the guarantee is

Priestwood Green homes and the weather
Historic houses like Cobham College (about 2.9 miles north-east) are a reminder that the area around Priestwood Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Culverstone Green Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Sole Street station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Where a wall is exposed, as many are in small places like Priestwood Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
