Sealant specialists in Westborough
How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. If you have smeared sealant across finishes from a rushed job and water staining near frames, panels or ceilings, we can put it right, whatever the surface. Searching for sealant specialists in Westborough? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes part of a day on a small job and longer where several buildings or phases are involved, and we clear our waste as we work. What matters most for a job in Westborough is a clear list of what needs doing, so send photographs of each area. You will then get a fixed price for the work.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.
- A suitable product for each joint goes in at the right depth and is tooled.
- A final walk-round, then the 12-month guarantee applies.
Getting the site ready
- Warn occupants and staff about the work

Questions we are asked in Westborough
Do hotels near Westborough have to close for sealant work?
In the majority of cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Will you take on work at estates like Guildford Industrial Estate, close to Westborough?
Yes. Our area takes in Westborough and its surroundings, with estates and business parks such as Guildford Industrial Estate included. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can you supply RAMS and insurance details?
We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can areas stay open during the work?
Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.

What else we do in Westborough
Working on commercial sites near Westborough
There are a good number of hotels within about 2 miles of Westborough. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter. Westborough is in the South East, one of the UK’s drier regions. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.
Offices and shops close to stations such as Guildford station (to the south-east of Westborough) tend to be busy all day, so sealant work is planned around opening hours. Refits at hotels like Asperion Hotel, 0.9 miles to the south-east of Westborough, bring joints at vanity tops, bars and reception desks that guests see every day.
Westborough is about 1 mile west of Guildford, in Surrey. Any commercial site in Westborough is covered, for single jobs and planned programmes alike. Westborough is one of 379 places we cover in Surrey. For work in that direction, see our Reading page (21 miles or so).

Common problems we fix in Westborough
In wet areas the enemy is normally mould rather than movement. Constant moisture, cleaning chemicals and weak extraction let mould grow into the sealant, and once established it rarely cleans out. The fix is a new bead of anti-mould sanitary silicone.
It’s worth sending us details if you spot any of the following:
- Smeared sealant across finishes from a rushed job
- Damp patches where an external joint has failed
- Shrunken sealant along kitchen worktops and splashbacks
- Black mould through washroom sealant that won’t clean off
In a retail centre such as Ladymead Retail Park, which lies east of Westborough, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish.
What your quote should include
- Proof of insurance
- Is the sealant right for the movement and the substrate?
- Their approach to joint depth and backing
- Their pre-qualification and accreditations
Why deal with it now?
Spot repairs have their place. If the rest of the bead is the same age and product, though, it’s usually close behind. We can price both options so you can decide on the facts. In a smaller place such as Westborough, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
What you get with us
- A Constructionline member, so easy to vet
- A fixed quote before work starts
- Coloured sealants to suit the setting, where available
- Over 20 years of commercial sealing

Work for main contractors and building owners
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Westborough can sit alongside others in a wider programme.
Building owners and managing agents use us on everything from one building to a spread of sites around Westborough. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Add sealant to the planned maintenance inspection list
- Check joints after other trades have worked nearby
- Keep abrasive pads and scrapers off resealed joints
- Make sure contractors see the asbestos survey before cutting out old mastic
Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.
An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to, which makes sound joints worth keeping on top of.
