About our window mastic in Tatsfield
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. Common call-outs are for rushed sealant from a window installation and rain getting in at the frame or under the sill, on uPVC windows, patio & French doors and composite doors.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Tatsfield is something to talk through when you book.
Our work is backed for twelve months, in Tatsfield and everywhere else we cover.

Questions from Tatsfield
Is Tatsfield in your area for window mastic?
Yes. Our work covers London and the South East, and Tatsfield is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Can parking be tricky for a visit in Tatsfield?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
How long will my window job take?
The work takes most of a day for a typical house, less for a few frames. Access and the amount of old mastic make the biggest difference.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes a morning for a couple of windows and a door, depending on how much there is to do. In Tatsfield, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit

Related advice
Window mastic in Tatsfield: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Titsey Place (about 1.4 miles south-west) are a reminder that the area around Tatsfield has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Charles Darwin School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Common problems we fix in Tatsfield
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
People generally contact us after spotting something like this:
- Gaps left after new windows were fitted
- Cold air getting in at the frame edge
- A bead that doesn’t match the frame
- Cracked sealant at the sill ends
For landlords with property near Oxted station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Landlords, agents and businesses in Tatsfield
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
What happens if it’s left?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Tatsfield, the repair is bigger than a sealant job.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.
What you get with us
- Every job guaranteed for a year
- Sanitary silicone with an anti-fungal additive in wet areas
