Commercial sealant contractors in Mortlake, done properly
How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. We work on floor and threshold joints, kitchen worktops and splashbacks and window and door perimeters, and the failures we’re asked to look at most are messy, uneven beads from earlier work that let the building down and earlier reseals applied straight onto the failed bead. Most enquiries from Mortlake start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
A lot of what we do in Mortlake 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, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Working on commercial sites near Mortlake
A good number of hotels sit less than 2 miles from Mortlake. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, and the work can be phased so the rest of the hotel keeps trading. Mortlake has at least three named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal; brand colours often come into it.
Occupiers with premises at both Kew Retail Park and Phoenix Trading Estate could have the sealant at each handled under one quote. Access in Mortlake needs thought: the ULEZ covers all of Greater London, and loading and parking are rarely simple. For premises near Mortlake station, which lies north-west of Mortlake, footfall is part of the plan: work is phased so shops and offices keep trading.

Questions about Mortlake
Do you work in London buildings with loading restrictions?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we will work to them. We allow for the ULEZ, which covers every borough
Does your area include sites such as Kew Retail Park, near Mortlake?
Yes. Estates, retail parks and business parks around Mortlake, Kew Retail Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Do you seal on top of existing 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.
Is it OK to apply fresh sealant over existing beads?
Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip.
Can you take on work for an FM or managing agent?
Yes. You can send details through our quote form, and we’ll confirm any paperwork you need with the quote.
What guarantee do you give on resealing?
The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.
How the quote is worked out
To price the job, we consider:
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
- The total length or number of joints
- Access and working height
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.
What we need to price the job
A few photos plus some basic facts will normally do. It helps to include:
- Anything awkward about access or site hours
- Any dates the work must fit around
- Any specification or named product
- The postcode of the building
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
Maintenance after handover
To get the most from the new sealant:
- Check sealant as part of routine building inspections
- Have extract fans checked so wet areas dry out
- Respect the cure time before reopening an area
- Ask cleaners to use a soft cloth and mild cleaner on sealant
Give fresh sealant time to cure before it’s cleaned, wetted or walked past. That time depends on the product, the temperature and the joint depth. Keeping signs or barriers up until then protects the finish.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.
Building owners, agents and FMs in Mortlake
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Surface by 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, and we’ll tell you if the detail calls for something else.
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal, room by room if that suits the building.
Doing it in-house
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
How a job runs
Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Where parts of the building must stay open, the work is phased.
- Old sealant is cut out completely, never sealed over.
- A suitable product for each joint goes in at the right depth and is tooled.
- We check the work with you, and the 12-month guarantee starts.
Before we start on site
- Tell us your opening times and when work is allowed
- Make sure the joints can be reached
- Point out any areas we must not close
