Camberley Window Mastic
We cover Camberley for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Old mastic that has gone black or come away
- A bead that does not match the frame
- Gaps left after new windows were fitted
About our window mastic in Camberley
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. We work on uPVC windows, patio & French doors and timber windows & doors, and common reasons people get in touch are gaps left after new windows were fitted and white mastic on grey or black frames.
Around Camberley, many houses have gained conservatories, French doors or replacement windows over time. Each one adds more joints to look after, and those joints age at different rates. Sills, frame heads and glazing joints are where leaks usually start.
There’s a 12-month guarantee on every job.

The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a few frames, or a day or more for a whole house from start to finish. For a job in Camberley, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

Advice
FAQs for Camberley
I let a flat near Camberley station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Can you do window mastic in Camberley?
Yes. Our work covers London and the South East, and Camberley is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear quote.
How long should I leave it?
Cure times vary by product. We tell you how long to leave it before we go.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
Can I paint over the new sealant?
That depends on the product. Silicone is not paintable, but some hybrid sealants are. Tell us if you are decorating and we’ll choose accordingly.
Where are you based?
We work from Crawley. Our applicators cover Camberley, along with the rest of our area.
Do you work for hotels and businesses?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- A door that needs adjusting, rehanging or new seals
- Damp coming through the wall itself rather than the frame joint
- A frame that has rotted at the joint
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
Surfaces we seal
- Timber windows & doors
- Window sills
- uPVC windows
- Patio & French doors
- Aluminium frames
- Composite doors
When to call us in Camberley
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
These are the problems we’re asked about most:
- Cracked sealant at the sill ends
- White mastic on grey or black frames
- Untidy mastic left by window fitters
- Old mastic that has gone black or come away
If you live in an older home near Church of St Paul, the joint between an old wall and a newer frame is generally the first place rain gets in.
What your quote should include
- Are they insured?
- How long to leave it before use
- Whether they seal over old material or remove it
- Which sealant they’ll use, and why

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Repaint timber before it’s bare
- Wipe condensation off the frames
- Keep jet washers away from the mastic
- Walk round the house once a year and look at the joints
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
What affects the quote in Camberley
There’s no set price list. What we look at:
- Any mould that needs treating
- The amount of work
- How many areas need sealing
- Which sealant suits the joint
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
