Facade sealing for Leybourne sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
How we handle facade sealing in Leybourne
Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, so the price covers the real job. The enquiries we see most involve cold air coming in at window perimeters and staining on stone next to old sealant, on perimeter joints where frames meet the structure, stone and brick facade joints and cladding panel joints. Whoever orders the work in Leybourne, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Construction in and around smaller places such as Leybourne 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.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What we’re called out for in Leybourne
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone, and the patch soon lifts.
Any of the following is a good reason to get the joints checked over:
- Gaps between rainscreen or cladding panels
- Perimeter sealant that has split or peeled away
- Water coming in around window frames
- Patch repairs that keep failing
When units on a site such as New Hythe Business Park, 1.4 miles north-east of Leybourne, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- Can the work be phased to keep areas open?
- Proof of insurance
- Is the sealant right for the movement and the substrate?
Owners, agents and contractors
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
Our process
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Rural sites near Leybourne may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We start with photos, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and both faces cleaned back.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- The finished joints are checked with you.
Getting the site ready
- Point out any areas we must not close
- Tell us what induction or permit system the site runs
- Arrange parking or a loading space
Ask for a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. For smaller jobs, photographs and a description will do.

Coping and flashing joints
Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first, and areas needing repair are flagged.
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Keep the sealant details on the building file
- Combine resealing with other works that need access
- Report water ingress at frames as soon as it shows
- Never let anyone seal over old sealant
Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade rather than sitting against the joints.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos.
Facade sealing in Leybourne: the local picture
There are several hotels within about 2 miles of Leybourne. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.
Building work at universities like University for the Creative Arts - Maidstone, 3.8 miles to the south-east of Leybourne, is often timed for the summer, mastic included. For contractors at a school such as Lunsford Primary School, sealing has to be finished before term starts.

Questions we’re asked in Leybourne
Is hospital work, at somewhere like Maidstone Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Can work at a site such as University for the Creative Arts - Maidstone fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
What type of sealant goes on window perimeters?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we’ll price the work to it.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Quoting for work in Leybourne
