Window mastic in Warfield Park, done properly
Frames and walls do not move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We are often asked to deal with black, perished sealant on frames and draughts coming in around windows and doors, on timber windows & doors, composite doors and window sills.
Homes around Warfield Park range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
Each job carries a 12-month guarantee, whatever its size.

Window mastic in Warfield Park: local notes
Warfield Park is part of Bracknell, one of the post-war new towns. With many homes from the post-war decades, replacement windows and doors are common. That mastic ages as well, and sills and frame heads are where leaks start. 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.
If you look after a building such as Whitegrove Primary School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to St Martin's Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near Martins Heron station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

How the job changes by surface
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. We will point out any rot we find, as a joiner will need to deal with it.
Honest limits
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
- Damp problems in the wall away from the window
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

How the visit works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a morning for a couple of windows and a door. For a job in Warfield Park, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive

Advice
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Questions from Warfield Park
Do you work for landlords with property near Martins Heron station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Will you come out to Warfield Park?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can you match the sealant to my frames?
Generally, yes. Mention the frame colour when you ask for a quote and we will match it as closely as we can.
Will new mastic stop draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Do you seal inside as well as outside?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.

What affects the cost of window mastic
You will get a clear quote before work begins. It’s based on:
- When we can work, for business premises
- The old material and how stubborn it is
- The product the joint needs
- The number and length of the joints
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- The rough size of the job
Every job is quoted individually, so the first step is telling us about yours. Simply call 0345 464 0079 or drop us an email and describe the job, and photos are welcome.
For landlords and businesses
For anyone letting property in or around Warfield Park, several properties can go on one quote. Send us the addresses and the work at each.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What happens if it’s left?
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly. In an older home around Warfield Park, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
