Mastic sealing in Kennington
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in, with backing rod setting the depth where it’s needed. Most enquiries involve leaks at window and door perimeters and a mix of products and colours from past repairs, on balcony and threshold joints, communal kitchens and washrooms and shopfronts below residential blocks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Kennington, preparation and product choice get the time they need.
In a London area such as Kennington, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building, which is why block-wide programmes make sense.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or email drawings and photos and we will come back to it.

Block-wide mastic in Kennington
The 2 miles around Kennington include two care or nursing homes. For owners and operators of care buildings, window perimeters and external joints are best renewed in planned phases around residents. For a London block, the agent or landlord normally handles notices to residents and access to flats. We fit the programme to your notice periods.
Churches, halls and community buildings such as Calvary Church of God in Christ are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. If you manage student housing near a university such as University of the Arts London, which lies west of Kennington, the summer turnaround is the time for mastic. If you look after a block within reach of Vauxhall station (less than half a mile north-west of Kennington), frame and balcony mastic can be renewed on one programme.

Aftercare for building managers
For the best life from the joints:
- Have the asbestos survey to hand for older buildings
- Log resealing dates block by block
- Make it easy for occupiers to report draughts
- Avoid piecemeal callouts where you can
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order so spending is spread.
When to bring in a specialist
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

From enquiry to sign-off
Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We inspect the joints, building by building, and record what has failed and why.
- We send a fixed quote that sets out the joints, the products and the programme.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- Old sealant is stripped and each face prepared back to firm material.
- Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.

Advice
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Any access equipment needed
- Removal of failed or old sealant
- Quantities, in metres or numbers
- Location, for remote and island sites
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- The product your specification calls for
- Approximate linear metres or a joint schedule
- Whether the building will be occupied during the work
- Asbestos survey details if the building is older
For a fixed quote, phone 01277 525 020 or send details through our quote form. Our quote form is another easy route.
Building owners, agents and FMs in Kennington
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
Questions we are asked in Kennington
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Do you work in occupied care homes around Kennington?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.
Can you work to our specification?
Yes. Send it with your enquiry, and we’ll price the work to it.
What will the job cost?
There isn’t a price list, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.
Different surfaces, different methods
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. Tell us your site hours and access windows and we will plan around them.
External movement joints
Failed sealant is removed, backing rod inserted to control depth and the joint resealed with a grade whose movement class fits.
