Surface by surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly and baths are loaded where appropriate before sealing.
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
Construction mastic in Ash Green
Refurbishment work needs a slightly different approach from new build. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. The enquiries we see most involve early adhesion failures on new external joints and missed perimeter joints on a new elevation, across internal decorators’ caulk, floor and skirting junctions and sanitary and kitchen joints. Most enquiries from Ash Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a site near Ash Green, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photos and the programme let us give a fixed quote.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Construction mastic around Ash Green: points for this area
Central London is about 32 miles from Ash Green. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme. Ash Green sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.
Further education sites such as Aldershot College (1.4 miles west of Ash Green) are extended and refurbished from time to time, with mastic often programmed into the summer break. Hotel extensions and refits, at places such as Hog's Back Hotel (1.3 miles south-west of Ash Green), normally run between busy periods, so the sealing is squeezed into short windows.
Ash Green is about 2 miles east of Aldershot, in Surrey. Ash Green sits inside our coverage and the rest of Surrey, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Surrey coverage takes in 379 places. We also cover Reading, some 18 miles away.

FAQs: Ash Green
Is a smaller place like Ash Green outside your area?
No. Places such as Ash Green are covered as much as the big towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Could you schedule work at a campus like University of Surrey - Manor Park Campus for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Will you stick to the specified products?
The specified product is what goes in. Any suggested alternative is put to you before anything changes.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
What happens if the weather stops external sealing?
External sealant needs a dry joint and a temperature within the product’s range. Frosty or damp mornings can hold up external sealing so we usually switch to internal work when that happens.
Is the mastic package guaranteed?
It’s backed by our 12-month guarantee, covering how we sealed. Keeping other trades off finished joints prevents most problems.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- The product specified
- Induction, permit and paperwork requirements
- Backing rod, priming and other preparation
- Whether old sealant has to be cut out first
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
What we need to price the job
However big the job, the same details help:
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
- Access details, including height
- Any specification or named product
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, speak to us on 01277 525 020 or send photos by email.
Common problems we fix in Ash Green
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly, so depth is controlled with backing rod or bond-breaker tape.
Look out for the following:
- Inconsistent sealant finishes from plot to plot
- Missed perimeter joints on a new elevation
- Oversized or tapered gaps around new frames
- Failed sealant in an existing building being refurbished
Units on estates such as Belle Vue Enterprise Centre, 1.4 miles west of Ash Green, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Before you book anyone
- Are they CHAS accredited or on Constructionline?
- The terms of the workmanship guarantee
- How the existing material will be dealt with
- Whether primer will be used where the manufacturer specifies it
Doing it in-house
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 where general trades tend to cut corners.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
