About our mastic sealing in Stone Copse
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. Most enquiries involve the same joint failures repeated across a portfolio and no planned programme for sealant, across window and door perimeters on blocks, shopfronts below residential blocks and external wall and movement joints. Facilities teams, main contractors and managing agents in Stone Copse tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
For owners with a single building near Stone Copse, we plan to finish in one visit where possible. Send photos of the frames and joints and we’ll give a fixed quote.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

What the job involves on each surface
External movement joints
The joint width has to suit the movement and the sealant’s capability, often around 2:1 width to depth, as the manufacturer advises.
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
When it isn’t the sealant
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Misted or failed double-glazed units
- Substrate edges that need repairing first
- Failed window or door frames, which need a window contractor
If you are not sure, just speak to us on 01277 525 020 or email the details over and we will give you a straight answer.
Surfaces we seal
- Balcony and threshold joints
- Communal entrances and stairwells
- External wall and movement joints
- Shopfronts below residential blocks
- Communal kitchens and washrooms
- Window and door perimeters on blocks
What happens if it’s left?
Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once and is simpler to manage and budget. Older rural buildings around Stone Copse move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Blocks and managed buildings in Stone Copse
Rainfall across the South East, Stone Copse included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Stone Copse lies roughly 52 miles out from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate.
Site managers at schools like Fir Tree Primary School and Nursery can fit frame mastic into the summer works. If you look after a block within reach of Newbury Racecourse station (1.5 miles south of Stone Copse), frame and balcony mastic can be renewed on one programme. If you’re responsible for a building such as Parish Church of St Mary, frame and door mastic needs the same attention as any other property.

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we look at:
- Whether the work must be split into stages
- Travel to remote or island sites
- The product specified
- How accessible the joints are
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Details that help us quote
The more we know, the firmer the quote. Helpful details to send:
- A wide shot and a close-up of the area
- What the building is and how it’s used
- Access details, including height
- Approximate linear metres or a joint schedule

Stone Copse: questions and answers
Will you take on work at estates like Turnpike Road Industrial Estate, close to Stone Copse?
Yes, sites like Turnpike Road Industrial Estate are within our area, along with the rest of Stone Copse. Photos and a short description are enough for a first look.
Is Stone Copse too far out for you?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How much does the work cost?
Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email drawings and photos.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
