How commercial sealant contractors works in WC1N
Most of the buildings we seal stay open while we’re there. Tell us your site hours and access windows and we’ll plan around them. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. The enquiries we see most involve weathered facade sealant that no longer flexes and window and door perimeter joints that have cracked open, across floor and threshold joints, external facade joints and washrooms and tea points.
When we get to site, we sign in, go through any site induction and check how permits are handled. 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.
- We begin with whatever information you have, whether that’s photos, a drawing or a list of locations.
- We work out why the joints have failed and fix a quote for the agreed scope.
- 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.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
How we quote
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What’s near Holborn
We work on buildings around British Library of Political and Economic Science, City Academy and The Yorkshire Grey pub. You’ll also find St Alban's Church of England Primary School (less than half a mile east), Lincoln's Inn Fields (under half a mile south-west), St Alban's Church (under half a mile east) and Elizabeth Garrett Anderson School (0.9 miles north). There’s a railway station in Holborn itself: Farringdon station. A little further out are Montfichet's Tower (0.7 miles south-east) and Brunswick Centre (0.5 miles north-west). Green spaces nearby include Barnsbury Wood and Ludgate Hill.
Where commercial joints are in WC1N
In WC1N, much commercial sealant work follows refits in shops, offices and hotels in places such as Holborn. 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 WC1N is part of the area we cover.
Holborn: Units at places like Brunswick Centre, 0.5 miles north-west of Holborn, are refitted as brands change, and the joints have to suit each new scheme. A business with units at Grand Vitesse Industrial Estate and Southwark Bridge Business Centre needn’t use two contractors for its sealant.
Why deal with it now?
Fixing joints complaint by complaint is a costly way to manage sealant. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We can help you prioritise, starting with the joints most likely to let water in.
Questions to ask before you book
- The named product and why it was chosen
- How they’ll work around occupants
- How the joint faces will be prepared and primed
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Signs you need commercial sealant contractors
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. By the time it shows, there can be two or three layers to cut out.
It’s worth sending us details if you spot any of the following:
- Wall and floor joints that have lost their seal
- Greasy, split joints in a kitchen or tea point
- Frame mastic that has hardened and come away from the wall
- Untidy joints in a reception, shop floor or lobby
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Walls or slabs moving more than any sealant can take
- Leaks from pipework, wastes or valves (that’s plumbing)
Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. WC1N can form part of a wider programme.
What affects the price in WC1N
Your fixed quote is built from the real scope. It takes account of:
- Specialist products, such as fire-rated or hygienic sealants
- Phasing around occupants
- The site’s rules and procedures
- Quantities, in metres or numbers
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.
What we need to price the job
It doesn’t need to be a full survey. These details are enough to start:
- The asbestos register, for older buildings
- The site address and postcode
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we’ll return a fixed quote you can plan around. If you have questions first, call 01277 525 020 or email a schedule or drawings.
Questions we’re asked in WC1N
Is it OK to apply fresh sealant over existing beads?
Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
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.
Can one contractor look after sealant on all our buildings?
Yes. Give us the sites and the scope at each, and we’ll put together a fixed quote and a sensible order of work.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you work for facilities managers and managing agents?
Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.
Do you work in WC1N?
Yes. We cover WC1N, and the simplest way to start is to give us a call on 01277 525 020 or email drawings and photos.
