About window & door mastic
Your questions about window mastic in Winkfield
Is Winkfield in your area for window mastic?
Yes, Winkfield is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing.
I let a flat near Ascot station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Do you work on first-floor windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
How do I get a quote for window mastic in Winkfield?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or send us an email and let us know what needs doing and where.
Do you take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Is it messy?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
Why it’s worth doing now in Winkfield
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Winkfield can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Window mastic in Winkfield: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as St Leonard's Hill (about 2.7 miles north-east) nearby, there’s older building stock in the area around Winkfield 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 is traditional sand mastic.
For landlords with property near Ascot station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near Church of St Mary, the joint between an old wall and a newer frame is normally the first place rain gets in.
Winkfield is about 3 miles north-east of Bracknell, in Windsor and Maidenhead.

Local landmarks in Winkfield

What the job involves on each surface
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We’ll tell you if that’s what we find.
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.
What we’re called out for in Winkfield
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
These are the problems we are asked about most:
- Water coming in at the bottom corners of a door
- Black, perished sealant on frames
- Cracked internal joints between frame and plaster
- Rushed sealant from a window installation
If you look after a building such as Winkfield St Mary's CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- What the cure time is
- Whether the sealant suits the joint
- Is the old sealant removed completely?
- Who turns up on the day
How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. In a small place like Winkfield, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
