Window mastic in Friday Hill, done properly
Homes in Friday Hill 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 have water coming in at the bottom corners of a door and cracked or shrunken mastic around the frame, we can put it right.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease normally says who is responsible for the windows, so it’s worth checking before booking, and access in Friday Hill is something to talk through when you book.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Friday Hill homes and the weather
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. 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.

DIY versus a professional finish
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: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Different surfaces, different methods
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.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Friday Hill, the repair is bigger than the sealant job would have been.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why choose Mr Mastic in Friday Hill

How we quote for window mastic
The price is agreed before any work begins. It takes into account:
- The product the joint needs
- Any mould that needs treating
- How easy the joints are to reach
- The old material and how stubborn it is
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
Asking for a quote
Before you ask for a quote, have a think about:
- Whether it has been sealed before
- Any access issues, like height or stairs
- A few photos by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or send us an email.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Friday Hill. It helps if you can point us to a visitor permit or a bay close to the door.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- 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.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints

Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll take it from there.

Signs you need window mastic in Friday Hill
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.
The problems people generally mention when they call include:
- Rushed sealant from a window installation
- Cracked sealant at the sill ends
- Gaps between the frame and the inside reveal
- Draughts coming in around windows and doors
If you live in an older home near Church of St Peter and St Paul, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
