How we handle construction mastic in Kitts End
Perimeter sealing outside needs a dry joint and the right temperature. Each sealant has a temperature range, and damp, frost or condensation on frames stops work. Internal areas can typically carry on while the outside waits. If you have existing joints on a refurb that need cutting out and resealing and external joints sealed in damp or cold conditions that are now failing, we can put it right, on cladding and panel joints, sanitary and kitchen joints and window and door perimeters alike. Whoever orders the work in Kitts End, the brief is usually 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 Kitts End 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. That covers our preparation and application, and if something we did falls short, we return to it.

After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Keep product details for future maintenance
- Don’t schedule sealing before decorators and flooring are done
- Share drawings and the specification as soon as possible
- Use the product the specification names
After we’ve sealed an area, it helps to keep other trades from damaging the joints. Fresh sealant needs its cure time before it’s cleaned, painted near or knocked; we confirm the time for each product.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out, and avoids a rush.
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Kitts End may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- Snags are cleared and the package signed off with our 12-month guarantee.

Your questions answered
Is Kitts End too small for you to travel to?
Not at all. Kitts End is within our area. London and every South East county are within our area. 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 at a site such as Wrotham Business Park, by Kitts End?
Yes, sites like Wrotham Business Park are within our area, along with the rest of Kitts End. A few photographs and the unit address let us price the work.
What guarantee comes with a mastic package?
It’s backed by our 12-month guarantee. Protecting sealed areas from following trades helps avoid damage.
Do you need to see the site first?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
