How we handle window mastic in Combe
Homes in Combe have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on aluminium frames, patio & French doors and window sills, and people most often call us about draughty joints inside around the window and white mastic on grey or black frames.
Around Combe, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Every job is covered by a one-year guarantee.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Questions from Combe
Can you help a landlord with a rental near Combe station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is Combe within the area you cover?
Yes, Combe is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Is the new sealant paintable?
Not normally, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
What does window mastic cost?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
How long will my window job take?
A handful of frames is a short visit. You’ll get a timescale with the quote.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
What happens on the day
The work is kept neat and contained to the joints we are treating. Expect the work to take a morning for a couple of windows and a door, and we explain the cure time before we leave. In a small place like Combe, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- 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.
How to prepare
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

Advice
Different surfaces, different methods
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. We will point out any rot we find, as a joiner will need to deal with it.
What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The number and length of the joints
- Whether the work is at height
- Whether there’s mould to deal with
- How much old sealant there is and how hard it is to remove
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
When you call or email, these details help:
- Any previous sealing or DIY work
- The rough size of the job
- Any access issues, like height or stairs
- Whether it’s a home or a business
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work and send you a clear quote.
Keeping the joints in good condition
Looking after new joints is easy:
- Ventilate rooms so frames don’t stay wet inside
- Keep paint and stain on wooden frames in good order
- Use gentle cleaners on frames and sealant
- Don’t use solvent cleaners on the joint
Silicone can’t generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Common problems we fix in Combe
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
It’s worth asking for a quote if you see:
- Gaps between the frame and the inside reveal
- White mastic on grey or black frames
- Draughts coming in around windows and doors
- Black, perished sealant on frames
Letting a property close to Combe station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

- How hidden problems are handled
- Who does the work, and how experienced they are

Window mastic in Combe: 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. With historic houses such as Blenheim Palace (about 1.9 miles east) nearby, there’s older building stock in the area around Combe as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Managing a site like Combe CofE Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to St Laurence's 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.
