What the job involves on each surface
Movement joints in walls and floors
Floor joints that take trolleys or forklifts need a tougher filler or sealant. We will recommend the right filler or sealant for the traffic and movement, and tell you if the edges need repairing first.
Facade and cladding joints
On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price, and we will confirm the colours available for the specified product.
Commercial sealant contractors for commercial buildings in Custom House
Most of the buildings we seal stay open while we’re there. Tell us your site hours and access windows and we will plan around them. That applies whether the building is an office, a shop, a hotel, a college or a care home. We work on kitchen worktops and splashbacks, window and door perimeters and external facade joints, and the failures we’re asked to look at most are wall and floor joints that have lost their seal and smeared sealant across finishes from a rushed job. A specialist sealant contractor works differently from a general builder: on jobs in Custom House, preparation and product choice get the time they need.
The most common commercial job in Custom House is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
For managing agents and FMs looking after premises in Custom House, access is normally the first question: booked loading, goods-lift times, the permit system and a place to stage materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Working on commercial sites near Custom House
Less than 3 miles from Custom House there are at least three named estates and business parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints. A 2-mile radius around Custom House takes in plenty of hotels. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, and the work can be phased so the rest of the hotel keeps trading.
For a shop at a centre such as Brocklebank Retail Park, which lies south of Custom House, tidy joints at counters and displays matter as much as the fixtures. Sites a few miles apart, such as Greenshields Industrial Estate and Saint Mark's Industrial Estate, can share one programme and one point of contact.

Quoting for work in Custom House
Quotes vary with the job. Expect it to depend on:
- The site’s rules and procedures
- Any access equipment needed
- Quantities, in metres or numbers
- Whether the work must be split into stages
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- Specification clauses that apply
- Access details, including height
- A wide shot and a close-up of the area
- Where the site is, with the postcode
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or use the quote form.
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes anything from part of a day on a short run of joints to several weeks on a large phased package. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- First, details come to us: photos, drawings or a schedule of the areas.
- Next comes a diagnosis and a fixed quote.
- Site hours, access windows and the order of areas are agreed before we start.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
What we need from you
- Let building users know which areas are affected
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed

Advice
Do you need commercial sealant contractors in Custom House?
External sealant takes a steady beating from the weather. UV hardens the surface while wind and rain work at the edges; in time the surface chalks, hardens and cracks. A hardened bead can’t follow the building any more.
These are often picked up first by site or facilities staff:
- Messy, uneven beads from earlier work that let the building down
- External beads that have gone brittle and cracked
- A top-up bead over failed sealant, now lifting
- Greasy, split joints in a kitchen or tea point
Refits at hotels like Sunborn Hotel (to the west of Custom House) bring joints at vanity tops, bars and reception desks that guests see every day.
What your quote should include
- The terms of the workmanship guarantee
- Will CSCS-carded applicators be on site?
- Can the work be phased to keep areas open?
- Is the sealant right for the movement and the substrate?
When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Walls or slabs moving more than any sealant can take
- A failed roof covering or waterproofing membrane
- Misted, cracked or failed glazing units (a glazier’s job)
If you’re not sure, just ring 01277 525 020 or email us and we will give you a straight answer.
What we seal
- Kitchen worktops and splashbacks
- Window and door perimeters
- Floor and threshold joints
- Movement joints in walls and floors
- External facade joints
- Washrooms and tea points
Custom House: questions and answers
Do you cover business parks and estates near Custom House, such as Greenshields Industrial Estate?
Yes, sites like Greenshields Industrial Estate are within our area, along with the rest of Custom House. Send details of the unit and the work through our quote form for a quick quote.
Do you take on jobs in Custom House where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them. All of Greater London is inside the ULEZ, and our planning allows for it
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Will the building have to shut during the work?
Most of the buildings we work in stay occupied. Only the area being sealed is closed, and the sequence is agreed in advance for as long as the cure needs.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
What guarantee do you give on resealing?
It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.
