How we handle window mastic in Breeds
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have a bead that doesn’t match the frame and mastic that has split away from the wall, we can help, whatever the surface.
Somewhere as small as Breeds, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How we quote for window mastic
The price is agreed before any work begins. It’s based on:
- The size of the job
- How easy the joints are to reach
- Any working-time requirements on site
- Which sealant suits the joint
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

- How many joints, rooms or windows are involved
- Whether it’s a home or a business

Do you cover Breeds for window mastic?
Yes, Breeds is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Do you work for landlords with property near Beaulieu Park station?

Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we’re done.
Do you need window mastic in Breeds?
Mastic ages in the weather. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Common reasons people contact us include:
- Gaps where the sill meets the wall
- Rain getting in at the frame or under the sill
- Sealant in the wrong colour for the frame
- Gaps between the frame and the inside reveal
If you look after a building such as Chelmer Valley High School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before booking
- Who does the work, and how experienced they are
- What guarantee comes with the work
- What insurance they hold
- How long to leave it before use
Why it’s worth doing now in Breeds
Choosing the product is half the job. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In a small place like Breeds, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before work begins.
Why us?
- Sealant colour chosen to suit
- An ARBOMaster approved applicator
- Full insurance on every job
- One-year guarantee on every job

What happens on the day
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are, and we explain the cure time before we leave. In a small place like Breeds, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

Advice
Aftercare tips
So the new joints stay in good condition:
- Air rooms to keep condensation down around windows
- Don’t use solvent cleaners on the joint
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Faulty window hardware
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Window sills
- Composite doors
- Patio & French doors

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
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.
Window mastic in Breeds: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Letting a property close to Beaulieu Park station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Church of SS Mary and Laurence, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
