Mill Hill questions
Do you work for landlords with property near Walmer station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Does living near the coast affect window mastic in Mill Hill?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you come to Mill Hill?
Yes. We cover Mill Hill, as part of our work across South East England, London and Scotland. For a quote, phone 0345 464 0079 or drop us an email.
Where are you based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Can you do the inside joint as well?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
What does window mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Window mastic in Mill Hill
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we will tell you. Typical jobs include gaps between the frame and the inside reveal and mastic that has split away from the wall, on uPVC windows, aluminium frames and window sills.
Homes around Mill Hill range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

- The surfaces are cleaned and left dry.

Advice
Windows and doors in Mill Hill
Mill Hill is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Walmer station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near St Richard, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Do you need window mastic in Mill Hill?
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
These are the problems we’re asked about most:
- Cracked sealant at the sill ends
- Mastic that has split away from the wall
- Untidy mastic left by window fitters
- A bead that does not match the frame
Managing a site like St Mary's Catholic Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. Around Mill Hill, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- Which sealant suits the joint
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear price for the lot.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Whether it has been sealed before
- The rough size of the job
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work before giving you a price.
Looking after it afterwards
So the new joints stay in good condition:
- Paint up to the joint, not over it
- Walk round the house once a year and look at the joints
- Don’t aim a pressure washer at the joints
- Wipe condensation off the frames
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.
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.
