Our commercial sealant contractors service in SE18
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: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. For sites in SE18, the quickest start is to phone 01277 525 020 or email a schedule or drawings with a list of addresses. We work on external facade joints, window and door perimeters and kitchen worktops and splashbacks, and the failures we’re asked to look at most are shrunken sealant along kitchen worktops and splashbacks and water staining near frames, panels or ceilings.
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it.
- 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.
- Site hours, access windows and the order of areas are agreed before we start.
- We strip the failed bead and prepare both faces of the joint.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
What affects the price in SE18

Commercial sealant contractors across SE18: the area picture
In SE18, much commercial sealant work follows refits in shops, offices and hotels in places such as Plumstead, Woolwich and Charlton. Where the joint is on show, a colour that suits the finish is part of the job.
Around the motorway corridors of the South East, business parks and industrial estates are common, and SE18 is part of the area we cover.
Plumstead: Units at places like Gallions Reach Shopping Park, 1.6 miles north of Plumstead, are refitted as brands change, and the joints have to suit each new scheme. Occupiers with premises at both Gateway Business Centre and Woolwich Dockyard Industrial Estate could have the sealant at each handled under one quote.
Surface by surface
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.
Window and door perimeters
Where frames meet the surrounding wall, sealant is the weather line. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.
Signs you need commercial sealant contractors
If sealant tears through its centre, it has failed cohesively. That typically means the joint stretched further than the product could cope with: a bead laid too thin, an over-stretched joint or the wrong movement class. The same product in the same joint tends to fail the same way.
Look out for the following:
- Leaks that seem to come through a sealant line
- Layers of sealant, all of them failing
- Weathered facade sealant that no longer flexes
- Black mould through washroom sealant that won’t clean off
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Suspect materials that need testing and specialist removal
- Leaks from pipework, wastes or valves (that’s plumbing)
- Cracking that needs a structural engineer to look at it
What affects the price in SE18
The price varies from site to site. It mainly depends on:
- Removal of failed or old sealant
- The product specified
- How much there is to seal
- Phasing around occupants
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- When you need the work done
- Anything awkward about access or site hours
- The asbestos register, for older buildings
- Where the site is, with the postcode
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to call the office on 01277 525 020 or send photos by email.
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. A poor seal in places like these tends to cost more to put right later.
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.
SE18: questions and answers
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
What guarantee do you give on resealing?
A 12-month guarantee covers the workmanship from handover. Looking after the joints as we advise helps them last.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Can you supply RAMS and insurance details?
The paperwork is agreed with the quote: RAMS, an insurance certificate and CSCS details are the usual requests. Our applicators are CSCS-carded.
Is SE18 in your area?
Yes. SE18 falls within our area, and you can call the office on 01277 525 020 or email drawings and photos to get started.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
