Commercial mastic work in Chelwood Common
If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: details in, a fixed quote back, the sealing done, then our 12-month guarantee. To get a programme moving in Chelwood Common, phone 01277 525 020 or send details through our quote form with the site addresses. Site teams most often ask us about layers of sealant, all of them failing and black mould through washroom sealant that won’t clean off, on kitchen worktops and splashbacks, movement joints in walls and floors and window and door perimeters. A specialist sealant contractor works differently from a general builder: on jobs in Chelwood Common, preparation and product choice get the time they need.
A lot of what we do in Chelwood Common is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.
Work in smaller places such as Chelwood Common tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What we’re called out for in Chelwood Common
Resealing over the top is a false economy we come across often. New silicone has nothing to key into so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.
It’s worth sending us details if you spot any of the following:
- Greasy, split joints in a kitchen or tea point
- Window and door perimeter joints that have cracked open
- Messy, uneven beads from earlier work that let the building down
- Black mould through washroom sealant that won’t clean off
Whatever the building in Chelwood Common, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.
What your quote should include
- Health and safety accreditation such as CHAS
- How long is the guarantee, and what does it include?
- Will failed sealant be removed rather than covered?
- Will CSCS-carded applicators be on site?

How the job changes by surface
Facade and cladding joints
Facade sealant failures can be hard to spot from the ground. Photos from a closer viewpoint help us price, with colours confirmed for the product chosen.
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean, and cleanability is part of what an inspector looks at. We seal to a neat, cleanable finish and work around service times you agree with us.
From enquiry to sign-off
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself usually taking part of a day on a small job and longer where several buildings or phases are involved. If others near Chelwood Common need work, visits can be combined. You’ll have a fixed quote before work starts.
- We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- We strip the failed bead and prepare both faces of the joint.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
Preparing the site
- Let us know about inductions and permits
- Let building users know which areas are affected
- Send asbestos survey details if the building is pre-2000

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Questions about Chelwood Common
Can you supply sealant in our brand colour for a site in Chelwood Common?
Yes, we can usually get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.
Is a smaller place like Chelwood Common outside your area?
Not at all. Chelwood Common is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Do you check for asbestos before removing sealant?
It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit typically takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. For bigger or phased jobs, we will set out a timescale with the quote.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
When it isn’t the sealant
We check first that sealant really is the fix. It won’t put right:
- Cracking that needs a structural engineer to look at it
- Old mastic that tests positive for asbestos
- A failed roof covering or waterproofing membrane
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.
Surfaces we seal
- Kitchen worktops and splashbacks
- External facade joints
- Floor and threshold joints
- Movement joints in walls and floors
- Washrooms and tea points
- Window and door perimeters
General trades versus a 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. Getting these wrong usually costs more in the end than doing them right.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Why act early in Chelwood Common
On many buildings the mastic was done by whichever trade was on site. A specialist applicator takes care of product choice, joint depth and preparation, and they’re where most failures begin. It shows over the following seasons rather than at handover. For buildings around smaller places like Chelwood Common, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
