Common questions from Cheam clients
Does a hotel in Cheam need to shut while its sealant is renewed?
In the majority of cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we’ll plan around them.
Will you take on work at estates like Kimpton Industrial Park, close to Cheam?
Yes, sites like Kimpton Industrial Park are within our area, along with the rest of Cheam. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member.
What guarantee do you give on resealing?
A 12-month guarantee covers the workmanship. Keeping joints clean and inspected helps them last well beyond that.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
How long does a job like this take?
It depends on the scope, though a typical visit normally takes a few hours for one area, or a planned series of visits across a bigger building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
How do you keep disruption to occupiers down?
It’s mostly about sequence: areas are phased, access windows agreed and enough washrooms or entrances left in use. Let us know what can’t close and we’ll work around it.
Commercial sealant contractors in Cheam
Inside a commercial building, sealant does a lot of quiet work: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike, matching the sealant to the location instead of using one product throughout. We work on window and door perimeters, kitchen worktops and splashbacks and washrooms and tea points, and the usual reasons a site gets in touch are hardened, chalky sealant on south-facing or exposed elevations and damp patches where an external joint has failed. Looking for mastic applicators who cover Cheam? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
The most common commercial job in Cheam is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.
Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Working on commercial sites near Cheam
Cheam has five care or nursing homes no more than 2 miles away. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean. The area within 2 miles of Cheam holds a number of hotels. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes; work is planned so the hotel keeps trading.
For premises near Cheam station (0.6 miles north of Cheam), footfall is part of the plan: work is phased so shops and offices keep trading. If you have premises on more than one site, say at Kimpton Industrial Park and Longmead Industrial Estate, one contractor and one quote can cover both. Units at places like The Ashley Centre, 2.7 miles south-west of Cheam, are refitted as brands change, and the joints have to suit each new scheme.

On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. In Cheam, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We start with the evidence: photographs, drawings or a look on site.
- You get a fixed quote covering removal, preparation and the new sealant.
- We agree the order of work, access windows and site hours with you.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- We hand back each area with its cure time and our 12-month guarantee.
Before we start on site
- Let building users know which areas are affected
- Send any specification or drawings in advance
- Share your working hours and any access restrictions

Should maintenance staff do it?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
How the job changes by surface
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, phasing the rooms so not every toilet is closed at once.
Shop fronts and retail fit-outs
Shop fits put sealant right in front of clients. Counters, display units, shopfront frames and floor trims all need a neat line, frequently colour-matched to the fit-out. Colour options are confirmed with the quote.
Cost factors for sealant joints
We price every job individually. The things that drive the figure:
- Phasing around occupants
- Induction, permit and paperwork requirements
- The size and state of each joint
- How much existing material needs removing
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.
Before you send an enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- Whether the building will be occupied during the work
- When you need the work done
- Photos of the joints, close up and from further back
- The postcode of the building
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Looking after the joints
Regular inspection catches problems early. In particular:
- Don’t let cleaning or traffic back on before the cure time is up
- Keep a record of which joints were resealed and when
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Make sure contractors see the asbestos survey before cutting out old mastic
Keep an eye out for other trades after we have gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. If that happens, call the office on 01277 525 020 or send details through our quote form and we’ll price putting it right.
Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Resealing early keeps the problem in the sealant and out of the building.
What happens if it’s left?
Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. Failed sealant in a building in Cheam can quickly affect neighbours, tenants or the floor below. Dealing with it early is simpler for everyone.
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
