How we handle window mastic in Earlswood
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on aluminium frames, patio & French doors and composite doors, and the jobs we see most are a bead that doesn’t match the frame and black, perished sealant on frames.
In a smaller place like Earlswood, some walls face open ground and catch the full force of the weather, 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 one-year guarantee in Earlswood and across Surrey.

Window mastic in Earlswood: local notes
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.
Rented homes near Earlswood (Surrey) station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as St John's Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Different surfaces, different methods
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.

Looking after it afterwards
To keep the joints looking good and working properly:
- Don’t use solvent cleaners on the joint
- Look round the frames every year or so
- Don’t aim a pressure washer at the joints
- Wash the frames with mild soapy water
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just phone 0345 464 0079 or email us.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What happens on the day
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a morning for a couple of windows and a door. In a smaller place like Earlswood, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Let us know if you’ve seen damp or leaks

Why it’s worth doing now in Earlswood
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In an older home around Earlswood, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Sanitary silicone with an anti-fungal additive in wet areas
- A choice of colours where the product allows

Is Earlswood in your area for window mastic?
Yes, Earlswood is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.
Do you cover smaller places like Earlswood?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you seal the gap between the frame and the plaster indoors?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Do you work for letting agents?
Yes, often. Several properties can go on one quote, and between tenancies is a good time for the work.
How long does it take to reseal the windows on a house?
Allow a few hours for a handful of frames, longer for a whole house. Access and the amount of old mastic make the biggest difference.
