Window mastic in Chilworth
Over two decades of sealing frames has taught us which products suit which walls. We are fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on timber windows & doors, composite doors and patio & French doors, and the jobs we see most are whistling draughts around closed windows and untidy mastic left by window fitters.
Around Chilworth, 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.
Your job is guaranteed for a year, as with all our work.

What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a morning for a couple of windows and a door. Somewhere like Chilworth needs a little journey planning: 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.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Before we arrive
- Mention any tricky access
- Keep children and pets away from the work area
- Move anything stored near the joints

When something else is needed
To be straight with you, some problems need a different trade:
- Condensation trapped between the panes

- Penetrating damp from a failed cavity tray or render
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.
What we seal
- Patio & French doors
- Composite doors
- Aluminium frames
- Window sills
- uPVC windows
- Timber windows & doors
When to call us in Chilworth
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Keep an eye out for any of the following:
- Cold air getting in at the frame edge
- Mastic that’s falling out in pieces
- Water coming in at the bottom corners of a door
- Gaps left after new windows were fitted
In the older streets around Church of St Thomas, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before booking
- Who turns up on the day
- Whether the sealant suits the joint
- What insurance they hold
- What happens if the job turns out different
How the job changes by surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that, where a rigid one would crack.
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We will point out any rot we find, as that’s a job for a joiner.
Chilworth homes and the weather
With historic houses such as Chilworth Manor (about 0.4 miles north) nearby, there’s older building stock in the area around Chilworth as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Chilworth station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Chilworth CofE (Aided) Infant School, the mastic around its windows and doors needs looking after like any other building’s.

A little further out are Guildford House (2.2 miles north-west) and Guildford Castle (2.1 miles north-west). Not far away are Silent Pool and St Martha's Hill.
Looking after it afterwards
So the new joints stay in good condition:
- Repaint timber before it’s bare
- Paint up to the joint, not over it
- Clean frames with a soft cloth and soapy water
- Check the mastic once a year
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or send us an email.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
Chilworth: your questions answered
Can you help a landlord with a rental near Chilworth station?
Yes. We work for landlords and agents as well as householders. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you do window mastic in Chilworth?
Yes. Our work covers London and the South East, and Chilworth is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
How long does it take to reseal the windows on a house?
A handful of frames is a short visit, while a whole house takes longer. We confirm the timing with your quote.
Will new mastic stop draughts?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months.
How do I get a quote for window mastic in Chilworth?
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.
What happens if it’s left?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Around Chilworth, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and send you a clear quote before we start.
