When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Cracked or spalling substrates that need repair before sealing
- Joints too narrow for the movement they take, which need redesign
- Damp caused by condensation inside the building

How we handle facade sealing in Wallington
Managing agents and owners in Wallington ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. If you have failed sealant on precast panel joints and perimeter sealant that has split or peeled away, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Wallington 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 Wallington is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Check the asbestos register before old mastic is disturbed
- Avoid patch repairs on failed facade joints
- Combine resealing with other works that need access
- Don’t wait for a second leak before calling
After heavy weather, check vulnerable elevations for signs of water inside. Catching a new leak early keeps the repair small.
Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. Repeating a faulty detail just repeats the failure.

Advice
Owners, agents and contractors
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
What the job involves on each surface
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.
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed using a sealant classified for that use.

Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
New build and refits around Wallington
Wallington is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Wallington lies roughly 34 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.
For a contractor working at a hospital such as Fairfield Hospital, which lies west of Wallington, perimeter and facade sealing is planned around patients and deliveries. With historic properties like Hinxworth Place, 4.9 miles north-west of Wallington, in the area, refurbishment work often meets old masonry that needs compatible sealants.

Questions about Wallington
Would you work within a site like Fairfield Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work to our programme on a site in or near Wallington?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Can staff carry on working while you’re here?
Typically, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Can you work in cold or wet weather?
Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, so we plan around the forecast.
How long does a job like this take?
That varies with the scale of the job, but the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
