About our facade sealing in Mersham
We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. Most enquiries involve discoloured or dirty facade joints and gaps between rainscreen or cladding panels, across cladding panel joints, shopfront frames and coping and flashing joints. Looking for mastic applicators who cover Mersham? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Sites around smaller places like Mersham can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How a job runs
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Mersham are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
What we need from you
- Tell us your opening times and when work is allowed
- Let us know about inductions and permits
- Tell staff and tenants when we will be in

Looking after the joints
Your facilities or cleaning team can help the joints last. Share these points with them:
- Add perimeter sealant to planned maintenance checks
- Insist on a full cut-out when joints are renewed
- Investigate damp beside windows promptly
- Record the product and colour used on each elevation
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.
Coordinate facade sealing with other external works. One set-up for several trades saves money.
Building and refurbishing in Mersham
Central London is about 52 miles from Mersham. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Mersham sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
On a healthcare site such as William Harvey Hospital (Ashford) (1.6 miles north of Mersham), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. With historic properties like Westenhanger Castle (4.7 miles east of Mersham) in the area, refurbishment work often meets old masonry that needs compatible sealants. Units on estates such as Mersham-le-Hatch Business Village (to the north-east of Mersham) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Mersham is about 3 miles south-east of Ashford, in Kent. Looking for facade sealing in Mersham? We can help. Across Kent, 931 places are covered, including Mersham. Sites around Brighton have their own page, about 50 miles away.

Around Mersham
Recent enquiries here include premises near The Farriers Arms and Poulton Wood, among other places. Mersham’s nearest station is Ashford International station, about 2.9 miles north-west. Well-known places in the area include Ashford Designer Outlet (2.6 miles north-west) and William Harvey Hospital (1.7 miles north-west). For a walk, there’s Hatch Park.
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.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
What happens if it’s left?
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once. Older rural buildings around Mersham move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Common questions from Mersham clients
Is Mersham too small for you to travel to?
Not at all. Mersham is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work on a hospital site such as William Harvey Hospital (Ashford)?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do you seal facades in winter?
Rain and frost can pause external sealing. We plan for weather and keep you updated throughout the job.
Can you quote from photographs?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
What the job involves on each surface
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and we’ll mention any edges that need repair.
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints rather than the system it surrounds.
Quoting for work in Mersham
A fixed quote reflects the actual work. It allows for:
- Working within restricted access windows

Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.
What to include in your enquiry
However big the job, the same details help:
- How the joints are reached, and at what height
- What the building is and how it’s used
- Whether an asbestos survey exists
- Your programme or deadline
