Surface by surface
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints.
How we handle facade sealing in Newington
A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. We work on perimeter joints where frames meet the structure, window and door perimeters and stone and brick facade joints, and the usual reasons a site gets in touch are gaps between rainscreen or cladding panels and failed seals around shopfront and entrance frames. A specialist sealant contractor works differently from a general builder: in Newington, that means joint design, primers and backing rod as standard.
Sites around smaller places like Newington can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photographs and the programme let us give a fixed quote.

Why it’s worth doing now in Newington
Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. Around Newington, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote when you are ready.

Building and refurbishing in Newington
Newington sits close to the coast, within about 2 miles. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Rainfall across the South East, Newington included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
Projects at colleges like Folkestone College, 2.3 miles east of Newington, tend to run to term dates, so the mastic is planned tightly. Extensions at sites like Royal Victoria Hospital (to the east of Newington) typically sit beside working departments, and the mastic follows strict access rules. With historic properties like Acrise Place (3.2 miles north of Newington) in the area, refurbishment work often meets old masonry that needs compatible sealants.
Newington is about 2 miles north-east of Hythe, in Kent. Anywhere in CT18, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Newington is one of 931 places in Kent on our list. For work in that direction, see our Brighton page.

Questions we’re asked in Newington
Our building in Newington is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is a hospital such as Royal Victoria Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Do you work in Newington?
Yes. We cover Newington, within our coverage of Greater London, South East England and Scotland. To discuss a job, phone 01277 525 020 or send photos by email.
What will the job cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can staff carry on working while you’re here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
