Commercial sealant contractors across SW18: what to expect
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure typically announces itself as a stained ceiling or an unhappy tenant. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. The enquiries we see most involve sanitary sealant that has gone black and patchy and gaps behind commercial kitchen worktops and sinks, on kitchen worktops and splashbacks, window and door perimeters and movement joints in walls and floors.
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish.

- Where parts of the building must stay open, the work is phased.

Commercial sealant contractors across SW18: the area picture
In SW18, much commercial sealant work follows refits in shops, offices and hotels in places such as Wimbledon, Clapham Junction and Battersea. Visible joints call for a matched colour and a clean tooled finish.
Around the motorway corridors of the South East, business parks and industrial estates are common, and we cover SW18 along with the rest of the region.
Wandsworth: On a business park such as Chartwell Business Park, which lies north of Wandsworth, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters. Sites a few miles apart, such as Chartwell Business Park and Hurlingham Business Park, can share one programme and one point of contact.
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:
- Water from a services leak rather than a joint
- Suspect materials that need testing and specialist removal
- Walls or slabs moving more than any sealant can take
Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Put external and wet-area joints on a regular inspection round
- Have extract fans checked so wet areas dry out
- Report cracked or peeling sealant early
- Ask fit-out and M&E contractors to report any sealant they disturb
Add the resealed joints to your planned maintenance inspections. A periodic look catches splits and lifting edges early. If anything looks wrong, phone 01277 525 020 or use the quote form with a photo.
Sealant installed at the same time usually fails in sequence. The first failures are often a warning about the rest, so it makes sense to look at the wider elevation or block. We’ll tell you which sealant joints need doing first and which can wait.
Doing it in-house
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Owners, agents and contractors
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in SW18 can sit alongside others in a wider programme.
Quoting for work in SW18
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Any access equipment needed
- Quantities, in metres or numbers
- Working within restricted access windows
- Travel to remote or island sites
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
Sending details for a quote
We can often quote from photos and a few details. Please tell us:
- Access details, including height
- Where the site is, with the postcode
- The type of building and who uses it
- Approximate linear metres or a joint schedule
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or email the details over.
Common questions from SW18 clients
Do you cover SW18?
Yes. We cover SW18, and you can ring 01277 525 020 or email us to get started.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Is failed sealant stripped out, or sealed over?
The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Can you take on work for an FM or managing agent?
Yes. FMs, managing agents and landlords are among our regular clients. Tell us how you issue work and we’ll fit in.
Will you just go over the old sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
