Construction mastic in Addlestone
Mastic tends to be one of the final packages before handover, so it lands at exactly the point the programme is tightest. We work as a mastic subcontractor to main contractors and developers with projects in Addlestone. Most enquiries involve internal caulk splitting as the building dries out and sealant knocked or painted over by other trades, on brick and block movement joints, sanitary and kitchen joints and window and door perimeters. A single leaking joint is often how a building in Addlestone first comes to us: we look at the rest while we are there and tell you what we find.
Around places like Addlestone, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or use the quote form and we’ll arrange a return visit.

Sites and facades in and around Addlestone
Addlestone is about 19 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Addlestone has plenty of hotels close by, all within 2 miles. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.
For contractors on a campus like Royal Holloway University, which lies north-west of Addlestone, facade and perimeter sealing has to fit around students and term dates. For contractors at a college like Brooklands Technical College - Weybridge Campus, 1.3 miles to the south-east of Addlestone, perimeters and internal sealant are timed for the holidays.

Why act early in Addlestone
A quick bead over a damaged joint can get an area past inspection, but it rarely lasts. Sealant can’t grip a contaminated or existing bead, and the defect comes back after handover. We cut out and redo the joint properly. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Questions about Addlestone
Can you take on a job at a hospital such as St Peter's Hospital A&E?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Can work at a site such as Royal Holloway University fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Addlestone in your area?
Yes. Addlestone falls within our area, and the simplest way to start is to speak to us on 01277 525 020 or email us.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Do your applicators hold CSCS cards?
We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Tell us what site paperwork you need and we will confirm with the quote.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
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.
What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Specifying the product where the designer hasn’t
- Rework caused by others damaging completed areas
- Frames fitted out of tolerance
If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think.
Surfaces we seal
- Sanitary and kitchen joints
- Internal decorators’ caulk
- Window and door perimeters
- Cladding and panel joints
- Floor and skirting junctions
- Brick and block movement joints
Common problems we fix in Addlestone
Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with. Better to raise it at the start than seal a joint that’s bound to fail.
Most enquiries start with one or more of the following:
- Sealant knocked or painted over by other trades
- Existing joints on a refurb that need cutting out and resealing
- Window and door perimeters that won’t pass inspection
- Inconsistent sealant finishes from plot to plot
New wings at hospitals like St Peter's Hospital A&E, 1.6 miles to the west of Addlestone, bring long runs of window and panel joints to seal.
Before you book anyone
- Whether their applicators hold CSCS cards
- Are they CHAS accredited or on Constructionline?
- Is the sealant right for the movement and the substrate?
- Do they follow the manufacturer’s priming guidance?
