Window mastic in Woodrow, done properly
Homes in Woodrow have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We’re often asked to deal with rushed sealant from a window installation and sealant in the wrong colour for the frame, on composite doors, uPVC windows and window sills.
Somewhere as small as Woodrow, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes most of a day for a typical house, less for a few frames for a typical job. In a small place like Woodrow, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- 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.
- Every joint is checked before we leave.
Preparing for the visit
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children

Related advice
Woodrow: your questions answered
Is Woodrow within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Amersham station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Is the work guaranteed?
Yes. Our one-year guarantee covers every job.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we will tell you.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch so we can plan the job.
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.
Why act early in Woodrow
The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. Older cottages and farmhouses around Woodrow can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Quotes for window mastic in Woodrow
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether the work is at height
- The size of the job
- Any mould that needs treating
- Any working-time requirements on site
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- The type of property
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Roughly how big the job is
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.
Woodrow homes and the weather
Historic houses like Hughenden Manor (about 4.6 miles west) are a reminder that the area around Woodrow has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of the Holy Trinity, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Curzon Church of England Combined School, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Amersham station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Clean frames with a soft cloth and soapy water
- Air rooms to keep condensation down around windows
- Repaint timber before it’s bare
- Keep drainage slots and sill grooves clear
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
What else we do in Woodrow
What the job involves on each surface
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.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
