Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Why act early in Devil's Den
On many buildings the mastic was done by whichever trade was on site. A specialist applicator takes care of product choice, joint depth and preparation, the three things that decide how long a joint lasts. It shows over the following seasons rather than at handover. Converted and older buildings near places like Devil's Den tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Some joints are best left to specialists: for instance 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.
How a job runs
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. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Devil's Den can be grouped with others nearby. You’ll have a fixed quote before work starts.
- You send photographs, drawings or a list of the joints and areas involved, or we arrange a site visit.
- Next comes a diagnosis and a fixed quote.
- Before anything is cut out, we agree access, timings and sequence.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
Getting the site ready
- Send your site hours and access windows
- Let us know about inductions and permits
- Send any specification or drawings in advance

Common questions from Devil's Den clients
Is Devil's Den too small for you to travel to?
Not at all. Devil's Den is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Will you take on work at estates like Barradale Farm Industrial Estate, close to Devil's Den?
Yes, sites like Barradale Farm Industrial Estate are within our area, along with the rest of Devil's Den. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
What guarantee do you give on resealing?
The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How do you keep disruption to occupiers down?
It’s normal for us to work in occupied buildings. Only the area being sealed is closed, and the sequence is agreed in advance for as long as the cure needs.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Owners, agents and contractors

Commercial premises in Devil's Den
Devil's Den sits in one of the drier corners of the country, the South East. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. Less than 3 miles from Devil's Den there are two named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies.
Shops and cafés around stations like Staplehurst station (1.8 miles south-west of Devil's Den) trade from early, so work is timed around them. On estates like Barradale Farm Industrial Estate (1.9 miles south-east of Devil's Den), the office and welfare end of each unit has its own sealant to maintain. Occupiers with premises at both Barradale Farm Industrial Estate and Orchard Industrial Estate could have the sealant at each handled under one quote.

Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Keep abrasive pads and scrapers off resealed joints
- Check joints after other trades have worked nearby
- Deal with small splits before they become leaks
- Have extract fans checked so wet areas dry out
Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.
Sealant installed at the same time typically fails in sequence. A few splits this year normally mean more next year, so it makes sense to look at the wider elevation or block. We’ll tell you which sealant joints need doing first and which can wait.
Surface by surface
Commercial kitchens and tea points
In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. They’re degreased thoroughly before resealing.
Movement joints in walls and floors
A trafficked floor joint needs a different product from a wall joint. The choice comes down to how much the joint moves and what runs over it; if the arrises are broken, we’ll say so before sealing.
