DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Window mastic for homes and businesses in Waldershare
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We’re often asked to deal with draughty joints inside around the window and a bead that doesn’t match the frame, on patio & French doors, timber windows & doors and uPVC windows.
Somewhere as small as Waldershare, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

Why it’s worth doing now in Waldershare
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In a small place like Waldershare, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.
What you get with us
- Neat joints and a tidy finish
- We agree the colour with you first

What window mastic looks like in Waldershare
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Goodnestone Park (about 4 miles north) nearby, there’s older building stock in the area around Waldershare as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around Church of St Pancras, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Eythorne Elvington Community Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Shepherds Well station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How it works
We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. The job usually takes most of a day for a typical house, less for a few frames, and we tell you how long to leave it before we go.

Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.

Aftercare tips
To keep the joints looking good and working properly:
- Paint up to the joint, not over it
- Ventilate rooms so frames don’t stay wet inside
- Avoid harsh chemicals near the mastic
- Wash the frames with mild soapy water
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
FAQs for Waldershare
Is Waldershare in your area for window mastic?
Yes. We work across London and the South East, and Waldershare is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
Do you work for landlords with property near Shepherds Well station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can I paint over the new sealant?
Not usually, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Is there any odour?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
