Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Facade sealing in Langley Green
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear. If you have perimeter joints where frames meet the structure and facade joints cracked through the middle, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Langley Green, that means joint design, primers and backing rod as standard.
In a smaller place such as Langley Green, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

How a job runs
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For a site in Langley Green, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- We remove the old bead and check the edges are sound.
- Faces are cleaned, primed where needed and backed.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Before we start on site
- Let building users know which areas are affected
- Clear stock, furniture or equipment away from the joints
- For older buildings, check the asbestos register before work

Langley Green: questions and answers
Is a smaller place like Langley Green outside your area?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Does your area include sites such as Basepoint Business Centre, near Langley Green?
Yes. Our area takes in Langley Green and its surroundings, with estates and business parks such as Basepoint Business Centre included. To start, just ring 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
Is it okay to overlay old mastic?
No. Overlaying is a shortcut that peels away quickly. We remove the failed sealant, clean the faces, set the depth and reseal.
How long does a job like this take?
It depends on the scope, though a typical visit usually takes a day or two for a few elevations, and longer where access has to be moved around the building. For bigger or phased jobs, we will set out a timescale with the quote.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
Can you work while the building is occupied?
In the majority of cases, yes. We phase the work so most of the building stays in use.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Render or concrete edges that have broken away
- Specialist high-level access methods
- Water getting in through cracked render or porous masonry
If you’re not sure, just call 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Mastic packages on Langley Green sites
Langley Green lies roughly 26 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. The planned town of Crawley is on Langley Green’s doorstep. Many of its original buildings are reaching the age for recladding and new windows, with mastic packages to match.
Hotels like The Maple Manor Hotel, 0.9 miles north-west of Langley Green, rarely close for long, so refurbishment mastic is phased floor by floor. Extensions at sites like Langley Green Hospital (psychiatric), less than half a mile to the east of Langley Green, typically sit beside working departments, and the mastic follows strict access rules. Projects at colleges like Crawley College (to the south of Langley Green) tend to run to term dates, so the mastic is planned tightly.
Langley Green is about 1 mile north of Crawley, in West Sussex. Our applicators travel to Langley Green for work on facade joints, handled exactly as we handle every other area.

What sets the cost
To price the job, we consider:
- The site’s rules and procedures
- How much there is to seal
- Location, for remote and island sites
- How accessible the joints are
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Details that help us quote
We can often quote from photographs and a few details. Please tell us:
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
- The product your specification calls for
- When you need the work done
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to give us a call on 01277 525 020 or use the quote form with what you know.
Why deal with it now?
The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. In a smaller place such as Langley Green, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
