Different surfaces, different methods
Fire-rated seals where specified
Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. Fire-stopping design and sign-off sit with the designer, fire engineer or building control; we install what’s specified.
Facade and cladding joints
Facade sealant failures can be hard to spot from the ground. Close-up photographs or a site visit tell us what’s needed.
Sealant specialists in Eton Wick
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. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. The enquiries we see most involve frame sealant that has cracked, shrunk or pulled away and movement joints packed with grit and debris, across washrooms and tea points, external facade joints and floor and threshold joints. Searching for sealant specialists in Eton Wick? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In an occupied building in Eton Wick, the job is planned so areas stay in use: we agree the order with you and hand back each area with its cure time.
Commercial sealant work around smaller places like Eton Wick tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What sets the cost
We price every job individually. The main factors are:
- Removal of failed or old sealant
- Site requirements such as inductions and permits
- Joint width, depth and condition
- Specialist products, such as fire-rated or hygienic sealants
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
A few photos plus some basic facts will normally do. It helps to include:
- Your programme or deadline
- Specification clauses that apply
- The type of building and who uses it
- Access details, including height
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or email us.
Questions we’re asked in Eton Wick
Does a hotel in Eton Wick need to shut while its sealant is renewed?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.
Is Eton Wick too small for you to travel to?
Not at all. Eton Wick is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
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.
What site paperwork can you provide?
We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.
Can you handle sealant work across several sites?
Yes. Send a list of addresses and what’s needed at each, and fixed prices follow, with a suggested sequence.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure.

Eton Wick has plenty of hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes.

What we’re called out for in Eton Wick
A good share of the joints we inspect were topped up instead of being renewed. Fresh sealant won’t stick to the old bead underneath. Getting back to a clean joint then means removing every layer.
Clients usually get in touch after noticing one or more of the following:
- Frame sealant that has cracked, shrunk or pulled away
- Gaps behind commercial kitchen worktops and sinks
- Sanitary sealant that has gone black and patchy
- Movement joints packed with grit and debris
A hotel such as Copthorne Hotel Slough - Windsor (1.2 miles north-east of Eton Wick) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.
What your quote should include
- Their approach to joint depth and backing
- How the joint faces will be prepared and primed
- How they’ll work around occupants
- Who will actually carry out the work
When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Faulty windows rather than failed perimeter sealant
- Roof leaks that only look like a joint problem
- Walls or slabs moving more than any sealant can take
If you are not sure, just give us a call on 01277 525 020 or email the details over and we will give you a straight answer before you book.
Joints and surfaces we work on
- Washrooms and tea points
- Kitchen worktops and splashbacks
- Floor and threshold joints
- External facade joints
- Movement joints in walls and floors
- Window and door perimeters
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Make sure contractors see the asbestos survey before cutting out old mastic
- Keep abrasive pads and scrapers off resealed joints
- Check joints after other trades have worked nearby
- Report cracked or peeling sealant early
Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early. Should something look amiss, you can ring 01277 525 020 or email us and send a picture.
Occupiers often notice failing sealant before the facilities team does, and it reflects on how the building is run. Planned replacement saves fielding the same complaint again and again.
