Commercial sealant contractors in Carlton Hill
Mastic Doctor has been sealing joints for businesses and contractors since 2005: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. The enquiries we see most involve wall and floor joints that have lost their seal and frame mastic that has hardened and come away from the wall, on floor and threshold joints, washrooms and tea points and movement joints in walls and floors. Most enquiries from Carlton Hill start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
We price commercial jobs in Carlton Hill from photos, drawings or a site visit, with the scope listed so everyone knows what’s included.
Sealant jobs for businesses in a place the size of Carlton Hill are often best grouped: shopfront, washroom, kitchen and any external joints done together. Fewer visits means less disruption to trading.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Do you need commercial sealant contractors in Carlton Hill?
A split down the middle of the bead tells a different story. That usually means the joint stretched further than the product could cope with because the bead was too thin, the joint over-stretched or the movement class wrong. Replacing it like for like rarely holds, which is why we look at the joint design as well.
Clients normally get in touch after noticing something like this:
- Messy, uneven beads from earlier work that let the building down
- Expansion joints with the sealant torn out
- Weathered facade sealant that no longer flexes
- Gaps behind commercial kitchen worktops and sinks
Occupiers with premises at both Freshfield Industrial Estate and Centenary Industrial Estate could have the sealant at each handled under one quote.

Maintenance after handover
Keep the joints in good shape with a few simple steps:
- On pre-2000 buildings, share the asbestos information before work starts
- Add sealant to the planned maintenance inspection list
- Keep abrasive pads and scrapers off resealed joints
- Check joints after other trades have worked nearby
Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. Your maintenance team can look at extract fans at the same time.
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.
Commercial sealant contractors in Carlton Hill: the local picture
Carlton Hill lies within about 1 mile of the sea. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. A matched colour is only half the brief on an exposed frontage. The South East is one of the drier parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.
For premises near Brighton station, which lies north-west of Carlton Hill, footfall is part of the plan: work is phased so shops and offices keep trading. A hotel such as Maon Hotel, less than half a mile to the south-east of Carlton Hill, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.
Carlton Hill is about 1 mile south of Brighton, in Brighton and Hove. We send applicators to Carlton Hill for sealant joints, handled exactly as we handle every other area. Carlton Hill is one of 29 places we cover in Brighton and Hove for sealant joints.

Carlton Hill: questions and answers
Is Carlton Hill too far out for you?
Not at all. Carlton Hill is within our area. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you cover business parks and estates near Carlton Hill, such as Freshfield Industrial Estate?
Yes. Our area takes in Carlton Hill and its surroundings, with estates and business parks such as Freshfield Industrial Estate included. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How many days will you need on site?
That varies with the scale of the job, though a typical visit normally takes part of a day on a small job and longer where several buildings or phases are involved. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Do you take on multi-site sealant work?
Yes. Send a list of addresses and what’s needed at each, and fixed prices follow, with a suggested sequence.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Leave it or put it right?
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. You notice the difference years later, not on the day. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Pricing sealant joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

What the job involves on each surface
Fire-rated seals where specified
Not every penetration suits a sealant. Other products, such as collars, wraps and batts, are specified for different services, so we’ll flag it if the detail needs a different product.
Window and door perimeters
The perimeter joint between a frame and the structure keeps rain out of the reveal. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.
When it isn’t the sealant
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Old mastic that tests positive for asbestos
- Roof leaks that only look like a joint problem
- Structural cracks or movement the joints weren’t designed for
If in doubt, call 01277 525 020 or send photos by email and we’ll say what we think.
Joints and surfaces we work on
- Kitchen worktops and splashbacks
