Facade sealing in Forty Green, done properly
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. If you have hard, chalky sealant that no longer flexes and facade joints cracked through the middle, we can help, whatever the surface. A specialist sealant contractor works differently from a general builder: in Forty Green, that means joint design, primers and backing rod as standard.
In the countryside around places like Forty Green, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Your questions answered
Can you take on a job at a hospital such as The Paddocks Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Forty Green too far out for you?
No. Places such as Forty Green are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Can you look at water coming in around a frame?
Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all, and we will tell you which.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Building and refurbishing in Forty Green
Forty Green lies roughly 38 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.
Units on estates such as Bandet Way Industrial Estate (3 miles west of Forty Green) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Historic houses such as Adwell House (to the south-west of Forty Green) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. New wings at hospitals like The Paddocks Hospital (to the east of Forty Green) bring long runs of window and panel joints to seal.

Why deal with it now?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, often turning up far from the joint. One visit to deal with every failing joint makes more sense than several trips to a place like Forty Green, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Our process
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Forty Green are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Getting the site ready
- Let us know about inductions and permits
- Arrange parking or a loading space
- Send asbestos survey details if the building is pre-2000

Looking after the joints
For the best life from the joints:
- Check the asbestos register before old mastic is disturbed
- Note when each elevation was last resealed
- Investigate damp beside windows promptly
- Walk the elevations once or twice a year
Record the sealant type and date on the building file. Future work can then match the product and colour.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.
Surface by surface
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint, not the framing or glazing itself.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.
Quoting for work in Forty Green
Your fixed quote is built from the real scope. It allows for:
- How much existing material needs removing
- Phasing around occupants
- Joint width, depth and condition
- Distance, for remote addresses
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Any specification or named product
- Photos of the joints, close up and from further back
- The site address and postcode
- The type of building and who uses it
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
