How the job changes by surface
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 finished to throw water off the joint.
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.
How we handle facade sealing in Keycol
Managing agents and owners in Keycol ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. Most enquiries involve weathered joints at frame-to-structure perimeters and staining on stone next to old sealant, on cladding panel joints, coping and flashing joints and perimeter joints where frames meet the structure. Facilities teams, main contractors and managing agents in Keycol tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Construction in and around smaller places such as Keycol 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.
Every job we finish is backed by a 12-month workmanship guarantee, in Keycol as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Your questions answered
Can work at a site such as Sittingbourne College fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is Keycol too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Should we check old sealant for asbestos?
For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder. Suspect material is left alone until it has been tested.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
How long does a job like this take?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Can you look at water coming in around a frame?
Yes. Photos help, and you can phone 01277 525 020 or email drawings and photos to arrange a visit. Many frame leaks are sealant failures, though not all.
From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Keycol, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Before we start on site
- Let building users know which areas are affected
- Tell us which areas need to stay in use
- Tell us your opening times and when work is allowed

Contractors’ notes for Keycol
Keycol lies within about 3 miles of the sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. There are a number of hotels within about 2 miles of Keycol. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
School extensions, at buildings such as Borden Church of England Primary School, normally run to the summer holidays, mastic included. When units on a site such as Newington Enterprise Centre, 1 mile north-west of Keycol, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Hospital estates such as Sittingbourne Memorial Hospital (to the south-east of Keycol) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Keycol is about 2 miles west of Sittingbourne, in Kent. Anywhere in ME9, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 931 places in Kent, from busy centres to rural villages. Sites around London have their own page, roughly 35 miles from Keycol.

Local landmarks in Keycol

What sets the cost
Your fixed quote is built from the real scope. It takes account of:
- Whether the work must be split into stages
- The total length or number of joints
- Whether old sealant has to be cut out first
- Distance, for remote addresses
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 quote when you are ready.
What to include in your enquiry
For an accurate fixed quote, we need a clear picture of the site. Send us:
- Asbestos survey details if the building is older
- The postcode of the building
- Specification clauses that apply
- Your programme or deadline
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.
Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Don’t wait for a second leak before calling
- Insist on a full cut-out when joints are renewed
- Keep pressure washers away from fresh sealant
- Share access with other external trades
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.
Tie resealing in with redecoration, cladding repairs or other access. Sharing the access keeps the cost down and cuts time on site.
What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Damaged frames that need replacing
- Providing access systems for the work
- Work on the window or framing system itself
If you’re not sure, just phone 01277 525 020 or send photos by email and we will give you a straight answer.
What we seal
- Coping and flashing joints
- Shopfront frames
- Cladding panel joints
- Window and door perimeters
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
General trades versus a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
