Facade sealing in Lewson Street
We don’t install glazing systems or replace glass. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. We work on window and door perimeters, shopfront frames and perimeter joints where frames meet the structure, and what we’re called in for most is weathered joints at frame-to-structure perimeters and cold air coming in at window perimeters. One point of contact handles commercial sealant work in Lewson Street from the first photos to the final walk-round, for single jobs and planned programmes alike.
Construction in and around smaller places such as Lewson Street 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.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

After the work
Once the work is signed off, a little attention goes a long way:
- Never let anyone seal over old sealant
- Confirm the survey covers external sealants in older buildings
- Share access with other external trades
- Keep the sealant details on the building file
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant.
Coordinate facade sealing with other external works. One set-up for several trades saves money and limits disruption.
Different surfaces, different methods
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. Primer goes on where the manufacturer specifies it for that substrate.
Diagnose, treat, sign off
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Lewson Street, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

Your questions answered
Is Lewson Street too small for you to travel to?
Not at all. Lewson Street is within our area. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work to our programme on a site in or near Lewson Street?
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.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Can the building stay open while you work?
In the majority of cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
How long does a typical visit take?
The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.
Will you check whether the sealant is causing the leak?
Yes. We check the sealant joints and report what we find as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Why deal with it now?
Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. Halls, stores and units around places like Lewson Street may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
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 we will put a fixed figure on it.

Building and refurbishing in Lewson Street
Lewson Street sits close to the coast, within about 3 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. Lewson Street sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
Historic houses such as Belmont House and Gardens, 3.3 miles to the south of Lewson Street, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. When a school such as Teynham Parochial Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
Lewson Street is about 3 miles west of Faversham, in Kent.

Doing it in-house
Some joints are best left to specialists: 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.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
