About our window mastic in Waterside
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. Common call-outs are for sealant in the wrong colour for the frame and whistling draughts around closed windows, on composite doors, aluminium frames and window sills.
Somewhere as small as Waterside, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, whatever its size.

Quotes for window mastic in Waterside
You’ll get a clear quote before any work starts. It’s based on:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- Mould in or behind the old joints
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What we do, step by step
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Waterside, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit

- Keep children and pets away from the work area

Questions from Waterside
Do you cover Waterside for window mastic?
Yes. We work across London and the South East, and Waterside is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
I let a flat near Amersham station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we’re fully insured.
Do you work on first-floor windows?
Yes, if safe access is possible. For high or awkward windows, we will tell you what access is needed.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
How do I get a quote for window mastic in Waterside?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or send us an email and tell us what needs doing and where.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What happens if it’s left?
The work is quick compared with the damage it prevents: it takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Waterside, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
What you get with us
- Tidy, careful work

Waterside homes and the weather
Historic houses like Chenies Manor House (about 3.4 miles south-east) are a reminder that the area around Waterside 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Amersham station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as Waterside Primary Academy, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Christ Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
When it isn’t the sealant
Before you book, it’s worth knowing the limits too:
- Faulty window hardware
- Worn gaskets, brush seals or a door that has dropped
- A failed sealed unit that has misted up
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
Joints and surfaces we work on
- Window sills
- Aluminium frames

How the job changes by surface
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We’ll point out any rot we find, as that’s a job for a joiner.
