Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Window mastic for homes and businesses in Lucas Green
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. We’re often asked to deal with untidy mastic left by window fitters and mastic that’s falling out in pieces, on uPVC windows, patio & French doors and aluminium frames.
In a village or hamlet like Lucas Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, whatever its size.

Windows and doors in Lucas Green
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Brookwood station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Bisley CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- When we can work, for business premises
- The type of sealant required
- How many rooms, windows or areas are involved
- How easy the joints are to reach
The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before any work starts.

When to call us in Lucas Green
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
If you can see any of these, it’s time to have the joints looked at:
- Rain getting in at the frame or under the sill
- Mastic that has split away from the wall
- Mastic that is falling out in pieces
- Rushed sealant from a window installation
For an older house near a landmark such as Holy Trinity, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- How much experience the applicator has
- Which colour the sealant will be
- Is the old sealant removed completely?
- Which sealant they’ll use, and why
When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Damp problems in the wall away from the window
- Soft or decayed wood in the frame
- Draughts through the window seals rather than the frame

Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.

Does the work come with a guarantee?

Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
How it works
Before we leave, we go over the finished joints with you. The work normally takes a few hours for a few frames, or a day or more for a whole house, depending on how much there is to do. For a village or hamlet like Lucas Green, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look at every frame and agree the list.
- 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.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit
- Clear items away from the joints we’re working on

Why it’s worth doing now in Lucas Green
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. Where a wall is exposed, as many are in small places like Lucas Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.
