How we handle facade sealing in Leeds
We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure on commercial buildings in Leeds. Coping and flashing joints are included where sealant is the specified fix. We work on perimeter joints where frames meet the structure, cladding panel joints and window and door perimeters, and what we are called in for most is facade joints cracked through the middle and gaps between rainscreen or cladding panels. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Leeds is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in and around smaller places such as Leeds is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Work we carry out in Kent comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Do you need facade sealing in Leeds?
Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead.
Look out for the following:
- Failed sealant on precast panel joints
- Damp patches beside frames after rain
- Old perimeter mastic that has dried out
- Staining on stone next to old sealant
When units on a site such as Park Wood Trading Estate (1.9 miles west of Leeds) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
What to look for in a quote
- Proof of insurance
- Will failed sealant be removed rather than covered?
- Their pre-qualification and accreditations
- How they handle RAMS and site documents
Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Inspect facade joints on a regular cycle
- Brief window cleaners about newly sealed joints
- Combine resealing with other works that need access
- Never let anyone seal over old sealant
After heavy weather, check vulnerable elevations for signs of water inside. An early report typically means a small reseal rather than a bigger repair.
Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and limits disruption.
Surface by surface
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. Primer goes on where the manufacturer specifies it for that substrate.
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building and need a durable external sealant.
Building and refurbishing in Leeds
Leeds has a number of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. At about 35 miles from central London, Leeds is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.
New wings at hospitals like KIMS hospital, 3.4 miles north-west of Leeds, bring long runs of window and panel joints to seal. For contractors on a campus like Canterbury Christ Church University, 3.5 miles north-east of Leeds, facade and perimeter sealing has to fit around students and term dates.
Leeds is about 4 miles east of Maidstone, in Kent. Our applicators travel to Leeds for work on facade joints. Leeds is one of 931 places in Kent on our list for facade joints. For work in that direction, see our London page.
We cover the ME17 postcode districts. Among the streets we cover are Brogden Crescent, Forge Lane and Gloriette Avenue, and sites on any of them can send details for a fixed quote. If your building is just outside Leeds, we cover Ashbank (1 mile north-east), Broomfield (1 mile east), Eyhorne Street (1 mile north-east), Chartway Street (2 miles south) and Kingswood (2 miles south-east). Nearby towns on our patch include Maidstone (4 miles west), Ashford (13 miles south-east), Sittingbourne (9 miles north-east), Tonbridge (15 miles west), Faversham (13 miles east) and Minster (15 miles north-east).
Around Leeds
Locally, jobs take us to sites close to The George Inn, among other places. For rail, the closest station is Hollingbourne station, roughly 1.6 miles north-east. Other landmarks nearby include Leeds Castle (1 mile east) and KIMS hospital (3.4 miles north-west). The countryside around Leeds includes Detling Hill.
For managing agents and facilities managers
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
We work for building owners and managing agents on everything from one building to a spread of sites around Leeds. One quote can cover more than one site, which keeps the paperwork simple.
From enquiry to sign-off
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. For work around Leeds, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Let us know about inductions and permits
- Point out any areas we must not close
Ask for a quote
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.
Advice
What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Joint width, depth and condition
- How accessible the joints are
- Working within restricted access windows
- How much existing material needs removing
A quote for facade joints depends on quantities, condition and access. Call for a quote.
Sending details for a quote
There’s no need for a formal survey. These details are enough to start:
- Asbestos survey details if the building is older
- Photos of the joints, close up and from further back
- Access details, including height
- When you need the work done
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or email the details over.
