- Missed perimeter joints on a new elevation
Need construction mastic in Kennington?
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Construction mastic in Kennington, done properly
The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over, so applicators arrive when areas are genuinely ready. That keeps the work right first time and saves rework. If you are dealing with a mastic package split between trades with no clear owner and perimeter gaps outside the sealant’s range, we can help. Whoever orders the work in Kennington, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Building work in places the size of Kennington is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Building and refurbishing in Kennington
Kennington lies roughly 48 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand. Kennington is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
Projects at schools like Kennington Church of England Academy work to term dates, so mastic is programmed tightly. Recladding or extending a unit at a site like Eurogate Business Park, 0.8 miles west of Kennington, brings panel joints and frame perimeters into the programme. Hospital estates such as The One Ashford Hospital, 2 miles to the south-east of Kennington, 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.
Kennington is about 2 miles north-east of Ashford, in Kent. We send applicators to Kennington for mastic packages, handled exactly as we handle every other area. Kennington is one of 931 places we cover in Kent for mastic packages. London is covered too, around 48 miles from Kennington.
Postcode districts covered here: TN24 and TN25. Among the streets we cover are Park Road, York Road and Ball Lane, and sites on any of them can send details for a fixed quote. Access to Kennington is via the A28 among other routes, so getting applicators and materials to site is simple. We also cover Bockhanger (1 mile south-west), Potters Corner (1 mile west), Boughton Lees (2 miles north), Godinton (2 miles south-west) and Willesborough (2 miles south).

Honest limits
We check first that sealant really is the fix. It won’t put right:
- Frame gaps too wide for sealant, which the installer needs to correct
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Damage to finishes by other trades after we have sealed
If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think.

How the job changes by surface
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, usually a low-modulus neutral-cure silicone.
Bathrooms, en suites and washrooms
Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere following the programme.
Owners, agents and contractors
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Why deal with it now?
Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. New sealant laid on old or dirty sealant has nothing to bond to and the defect reappears in the defects period. Damaged joints are removed and resealed from clean faces. For buildings in places like Kennington, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Questions we are asked in Kennington
Is a hospital such as The One Ashford Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you work around term dates at a campus such as Ashford College?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you quote from photos?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
What joints do you seal on a new build?
The scope comes from the specification and drawings, but frames, sanitary, kitchens, caulk where specified and snagging are typical.
From enquiry to sign-off
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it.
