Common questions from Westbrook clients
Could you schedule work at a campus like TOPS Vocational College for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Will you take on work at estates like All Saints Industrial Estate, close to Westbrook?
Yes, sites like All Saints Industrial Estate are within our area, along with the rest of Westbrook. Photos and a short description are enough for a first look.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Is colour matching possible?
That depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Can staff carry on working while you’re here?
In the majority of cases, yes. We phase the work so most of the building stays in use.
Construction mastic in Westbrook, done properly
Mastic tends to be one of the final packages before handover, so it lands at exactly the point the programme is tightest. Mastic Doctor takes on mastic packages for main contractors and developers, following the trades through the building as rooms and elevations become ready. If you’re dealing with frame perimeters left unsealed or poorly sealed and a mastic package split between trades with no clear owner, we can put it right. A single leaking joint is often how a building in Westbrook first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Building work in places the size of Westbrook is typically small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How the job changes by surface
External facade and movement joints
Many facade substrates need a primer before sealing. We prime where the manufacturer specifies, and seal only with a dry joint inside the product’s temperature range.
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line and baths are loaded where appropriate before sealing.
Facades, frames and programmes in Westbrook
With the shore within about 1 mile, Westbrook counts as a coastal location. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, so joint design, primers and product choice deserve extra care. Westbrook has a good number of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For contractors refurbishing units at places like All Saints Industrial Estate, which lies east of Westbrook, the mastic covers cladding panels, roller-door and window perimeters. New wings at hospitals like Queen Elizabeth The Queen Mother Hospital (to the south-east of Westbrook) bring long runs of window and panel joints to seal. Further education sites such as TOPS Vocational College, 1.2 miles east of Westbrook, are extended and refurbished from time to time, with mastic often programmed into the summer break.

Looking after the joints
For the best life from the joints:
- Put any product change through the designer first
- Brief following trades on areas that have been sealed
- Keep product details for future maintenance
- Keep scrapers and abrasive pads off new beads
At handover, keep the product details with the O&M information. That helps the building owner maintain the joints later, and tells you what to reseal with. Tell us what records you need and we’ll confirm with the quote.
A missed perimeter seal on one window can wet the reveal and the plaster inside. On a new building that means remedial work after decorating and possibly a delayed handover. A check of every frame before decorators start is worth the time.
Site staff or a sealant specialist?
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.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Diagnose, treat, sign off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. If neighbouring businesses or buildings around Westbrook need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- We price from the drawings, specification and programme you send.
- We return a fixed quote that ties the mastic package to your programme.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Joints are cleaned, primed where the maker requires it, backed and sealed to the specification.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
What we need from you
- Let us know about inductions and permits
- Tell us which areas need to stay in use
- Tell us your opening times and when work is allowed
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Advice
What happens if it’s left?
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 reappears in the defects period. We cut out and redo the joint properly. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
