Window mastic for homes and businesses in Pitshanger
Homes in Pitshanger have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you are dealing with cold air getting in at the frame edge and black, perished sealant on frames, we can put it right.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Pitshanger as anywhere.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Landlords, agents and businesses in Pitshanger
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
How the job changes by surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Make sure the drainage slots are not blocked
- Look round the frames every year or so
- Don’t aim a pressure washer at the joints
- Wipe condensation off the frames
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 drop us an email.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
FAQs for Pitshanger
Is parking an issue for window mastic in Pitshanger?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
I let a flat near Castle Bar Park station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
How long before the joint can be used?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Do you come to Pitshanger?
Yes. We’re based in Crawley and work across South East England, London and Scotland.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.

Window mastic in Pitshanger: local notes
With historic houses such as Pitzhanger Manor (about 1.1 miles south) nearby, there’s older building stock in the area around Pitshanger as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Schools such as North Ealing Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Castle Bar Park station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How the visit 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. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

Advice
What we can’t put right
Sealant is not the answer to every problem, and we’ll tell you before we start. Sealant won’t put right:
- Damp coming through the wall itself rather than the frame joint
- Draughts through the window seals rather than the frame
- A frame that has rotted at the joint
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
What we seal
- Aluminium frames
- Patio & French doors
- Window sills
- Composite doors
- Timber windows & doors
- uPVC windows
Common problems we fix in Pitshanger
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
Signs it’s time to call us include:
- Gaps left after new windows were fitted
- Hard, cracked sealant around windows
- Rain getting in at the frame or under the sill
- Sealant in the wrong colour for the frame
Pitshanger is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
