Telham Window Mastic
Window and door frames in Telham need attention? We cut out the old, prepare the joints and apply the right sealant.
- A bead that doesn’t match the frame
- Cold air getting in at the frame edge
- Draughty joints inside around the window
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door and we leave things clean and tidy. For a village or hamlet like Telham, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Preparing for the visit
- Clear items away from the joints we’re working on
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in

Window mastic for homes and businesses in Telham
Homes in Telham have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Common call-outs are for cold air getting in at the frame edge and gaps left after new windows were fitted, on patio & French doors, window sills and aluminium frames.
Homes in small places like Telham often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, it’s backed by our 12-month guarantee in Telham and across East Sussex.

What affects the quote in Telham
The quote reflects the job in front of us. We take into account:
- The number and length of the joints
- How easy the joints are to reach
- The product the joint needs
- How many rooms, windows or areas are involved
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Helping us quote
To make quoting easier, please include:
- If someone has resealed it before
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
Aftercare tips
After the cure time, these simple habits help:
- Walk round the house once a year and look at the joints
- Do not paint over the silicone
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Work for landlords, hotels and businesses
If you manage several properties in or around Telham, several properties can go on one quote. Send us the addresses and the work at each, and photos by email help.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Soft or decayed wood in the frame
- Condensation trapped between the panes
- A sash or casement that will not close properly
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.

What the job involves on each surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
DIY sealant or a professional job?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
Window mastic in Telham: local notes
With historic houses such as Durhamford Manor (about 2.4 miles north) nearby, there’s older building stock in the area around Telham as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For site and facilities teams at buildings such as Claverham Community College, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Battle station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near Chapel of the Ascension, the joint between an old wall and a newer frame is generally the first place rain gets in.

Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Do the sealants smell?

Where is Mr Mastic based?
We work from Crawley. We cover Telham and the rest of East Sussex, along with the rest of our area.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Can you seal the gap between the frame and the plaster indoors?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
