Construction mastic for commercial buildings in Kennington
We work to the specification and the programme rather than whatever product is to hand. If a product is named, that’s what goes in, and if an alternative is proposed, it goes to you for acceptance first. Backing, primer and depth follow what the sealant maker sets out so the detail on the drawing is what ends up on site. We work on cladding and panel joints, sanitary and kitchen joints and floor and skirting junctions, and the failures we are asked to look at most are a long mastic snag list close to completion and caulk cracking where joints are moving more than expected. Searching for sealant specialists in Kennington? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
In a smaller place such as Kennington, construction tends to mean small housing schemes, conversions and extensions to community buildings. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email drawings and photos and we will arrange a return visit.

Why it’s worth doing now in Kennington
Some packages split mastic across the window fitter, kitchen fitter and plumber. In practice it often means different standards, gaps in responsibility and snags nobody owns. A single mastic package gives one point of responsibility and a consistent finish. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Why us?
- Health and safety: CHAS accredited
- 12-month guarantee on workmanship

Kennington: questions and answers
Do you cover business parks and estates near Kennington, such as Sandford Lane Industrial Estate?
Yes. Our area takes in Kennington and its surroundings, with estates and business parks such as Sandford Lane Industrial Estate included. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Is Kennington too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Is colour matching possible?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Can you seal external joints in wet or cold weather?
Conditions have to suit the product before external work starts. Sealing in poor conditions risks adhesion failure so it’s better to wait.
Can you clear a mastic snag list before handover?
Yes. Damaged, missed or untidy joints are stripped and done again properly, working to your handover date.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
When it isn’t the sealant
Honesty saves time and money. New sealant won’t cure:
- Faulty frames rather than failed sealant
- Joint design decisions that belong to the architect or engineer
- Joints damaged after sign-off by following trades
If you’re not sure, just call 01277 525 020 or email us and we’ll give you a straight answer.
Surfaces we seal
- Internal decorators’ caulk

Diagnose, treat, 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. What matters most for a job in Kennington is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.
- We walk the site or review drawings to understand the package.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- We seal plot by plot or floor by floor in line with the programme.
- Problems we find, such as oversized gaps, are raised straight away.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
What we need from you

Facades, frames and programmes in Kennington
Rainfall across the South East, Kennington included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager. Plenty of hotels sit less than 2 miles from Kennington. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
Work at a hotel such as Oxford Thames Hotel, 0.6 miles east of Kennington, tends to be programmed around bookings, mastic included. For contractors at a college like Abingdon & Witney College: Abingdon Campus, 2.8 miles south-west of Kennington, perimeters and internal sealant are timed for the holidays.

Different surfaces, different methods
External facade and movement joints
Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it.
Bathrooms, en suites and washrooms
On multi-unit schemes, consistency matters across hundreds of bathrooms. A single team keeps the standard consistent, plot by plot or floor by floor.
Signs you need construction mastic in Kennington
On a live site, contamination is the biggest threat to a new joint. Dust, film adhesive, damp and grease on the joint faces prevent a proper bond, so preparation matters as much here as on a reseal.
Any of the following is a good reason to get the joints checked over:
- Cracks opening in caulked internal joints
- New external sealant already peeling away
- Existing joints on a refurb that need cutting out and resealing
- A mastic package split between trades with no clear owner
Recladding or extending a unit at a site like Sandford Lane Industrial Estate (to the south-east of Kennington) brings panel joints and frame perimeters into the programme.
