How we handle facade sealing in Forty Hill
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause. If the evidence points away from the sealant, we say so before quoting. If you are dealing with unsightly perimeter sealant on a visible elevation and gaps between rainscreen or cladding panels, we can help, whatever the surface. A single leaking joint is often how a building in Forty Hill first comes to us: we look at the rest while we’re there and tell you what we find.
Building sites in London tend to be tight: limited storage, booked deliveries and access shared with other trades. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
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 spell out the cover before we begin.

Keeping the joints sound
A few simple habits keep the new joints working:
- Never let anyone seal over old sealant
- Record the product and colour used on each elevation
- Walk the elevations once or twice a year
- Investigate damp beside windows promptly
Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly with a compatible product.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones behind the facade.
Mastic packages on Forty Hill sites
Site traffic in Forty Hill falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed. There are a number of hotels within about 2 miles of Forty Hill. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For a contractor at a hotel such as Holtwhites Hotel, 1 mile to the south-west of Forty Hill, the mastic often has to be finished before a reopening date. New wings at hospitals like St Michael's Community Hospital (0.8 miles west of Forty Hill) bring long runs of window and panel joints to seal. For contractors at a school such as Worcesters Primary School, sealing has to be finished before term starts.
Forty Hill is about 1 mile north-east of Enfield, in Greater London. Across the EN1 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Our Greater London coverage takes in 764 places. We also cover London, around 12 miles from Forty Hill.

Leave it or put it right?
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

Cost factors for facade joints
To price the job, we consider:
- Location, for remote and island sites
- Which sealant the job calls for
- Access and working height
- Whether old sealant has to be cut out first
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Details that help us quote
The more we know, the firmer the quote. Helpful details to send:
- Approximate linear metres or a joint schedule
- Specification clauses that apply
- When you need the work done
- The postcode of the building
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

How a job runs
Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. 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.
- We look at the joints, the drawings and the access before pricing.
- 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.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Preparing the site
- Point out parking and an unloading spot
- Point out any areas we must not close
- Send asbestos survey details if the building is pre-2000

Owners, agents and contractors
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Doing it in-house
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Questions we’re asked in Forty Hill
