Leave it or put it right?
Sealant is often treated as an afterthought by the trade that fitted the element. Choosing the product, setting the depth and preparing the faces are what a specialist brings, and they’re where most failures begin. It shows over the following seasons rather than at handover. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
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.
Why appoint us
- CHAS accredited contractor
- One phone line for London, the South East and Scotland

Sealant specialists in Three Mills
How long a joint lasts is decided before any sealant leaves the gun. Silicone has no grip on cured silicone, so the failed bead is cut out completely. Primer is used wherever the manufacturer calls for it on that surface. The enquiries we see most involve window and door perimeter joints that have cracked open and damp patches where an external joint has failed, across kitchen worktops and splashbacks, movement joints in walls and floors and floor and threshold joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Three Mills, that means joint design, primers and backing rod as standard.
A lot of what we do in Three Mills is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

What we are called out for in Three Mills
Resealing over the top is a false economy we come across often. New silicone has nothing to key into, so the top layer lifts, holds water and hides what’s going on. Getting back to a clean joint then means removing every layer.
What tends to prompt an enquiry:
- Leaks that seem to come through a sealant line
- Greasy, split joints in a kitchen or tea point
- Frame mastic that has hardened and come away from the wall
- Sanitary sealant that has gone black and patchy
Occupiers with premises at both Crescent Court Business Centre and Datapoint Business Centre could have the sealant at each handled under one quote.

Three Mills: questions and answers
Do hotels near Three Mills have to close for sealant work?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.
Can you work at a site such as Crescent Court Business Centre, by Three Mills?
Yes. We cover Three Mills and the area around it, including industrial estates, business parks and retail parks such as Crescent Court Business Centre. Photos and a short description are enough for a first look.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Does commercial sealant work come with a guarantee?
A 12-month guarantee covers the workmanship. Looking after the joints as we advise helps them last.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Could the old sealant in an older building contain asbestos?
Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Surface by surface
Movement joints in walls and floors
A trafficked floor joint needs a different product from a wall joint. We will recommend the right filler or sealant for the traffic and movement.
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.
Owners, agents and contractors
Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Our process
Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Planning a London job such as one in Three Mills starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- You send photos, drawings or a list of the joints and areas involved, or we arrange a site visit.
- 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.
- We fit backing to the right depth, prime where specified and lay the new bead.
- Each area is inspected, signed off and backed by our 12-month guarantee.
Preparing the site
- Warn occupants and staff about the work
- Arrange parking or a loading space
- Tell us which areas need to stay in use

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Brief cleaning contractors to avoid scourers and blades on sealant
- Keep a record of which joints were resealed and when
- Look at the sealant around anything that has been moved or replaced
- Add sealant to the planned maintenance inspection list
In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, and mould follows damp. It’s worth having fans checked while the sealant is fresh.
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, so sound, smooth joints matter.
Commercial sealant contractors around Three Mills: what changes locally

Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean; colours can be chosen to suit the interior.
