Window mastic for homes and businesses in Old Warren
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. If you have mastic that has split away from the wall and black, perished sealant on frames, we can put it right, on uPVC windows, aluminium frames and patio & French doors alike.
In a village or hamlet like Old Warren, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Every job comes with our 12-month guarantee, wherever you are in West Berkshire.

How the job changes by surface
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.

How much does window mastic cost in Old Warren?
There’s no set price, as it 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.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Can you do several jobs on one visit?
Yes. Just list everything you need and you will get one quote.

What affects the cost of window mastic
We quote each job individually. These are the things that affect it:
- Whether there’s mould to deal with
- The type of sealant required
- Whether old sealant or filler has to be cut out
- The size of the job
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Access, such as stairs, a lift or height
- The rough size of the job
- What’s wrong with the joints now
- If someone has resealed it before
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 come back to you with a quote.
What happens if it’s left?
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Around Old Warren, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.
Why us?
- White, clear, grey or another colour, product permitting
- Every job guaranteed for a year

Frames and glazing around Old Warren
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like The Vyne (about 4.8 miles south) are a reminder that the area around Old Warren has older buildings as well as new. 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 Aldermaston station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Common problems we fix in Old Warren
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
The problems people normally mention when they call are:
- Cracked internal joints between frame and plaster
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
- Damp patches on the reveal after heavy rain
Homes close to The Parish Church of St.Saviours include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

The process
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take most of a day for a typical house, less for a few frames. For a village or hamlet like Old Warren, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- 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
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive
