About our mastic sealing in Kidbrooke
We diagnose before we prescribe: 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. Site teams most often ask us about the same joint failures repeated across a portfolio and complaints coming in block by block, across external wall and movement joints, window and door perimeters on blocks and balcony and threshold joints. Looking for mastic applicators who cover Kidbrooke? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
For managing agents in Kidbrooke, resident access, notice periods and the building’s rules shape the job. We work to the agent’s notice and access plan, so residents know what’s happening.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

How the job changes by surface
Communal areas
Low-level communal joints get damaged more than most, so they often need renewing sooner.
Window and door perimeters on blocks
Perimeter joints on blocks are best done elevation by elevation or block by block. Access is agreed with you before the quote is fixed.
When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Masonry that has broken away beside the joint
- Broken glass or failed sealed units
- Leaks through the frame itself rather than the perimeter
If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think.
Joints and surfaces we work on
- Window and door perimeters on blocks
- Communal entrances and stairwells
- Shopfronts below residential blocks
- Balcony and threshold joints
- External wall and movement joints
- Communal kitchens and washrooms
When to bring in a 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.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Frames, entrances and external joints in Kidbrooke
There are five care or nursing homes within about 2 miles of Kidbrooke. Owners of care premises can bring window and door mastic into a phased programme planned around the home. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We work to your notice and access plan.
For a school such as Henwick Primary School, perimeter mastic on windows and doors is a holiday job. If you manage student housing near a university such as University of Greenwich - Avery Hill, which lies south-east of Kidbrooke, the summer turnaround is the time for mastic. If you own or manage units on a site such as Stone Lake Retail Park, 1.7 miles to the north of Kidbrooke, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Our process
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- A building-by-building inspection lists the failed joints.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready
- Point out parking and an unloading spot
- Confirm the product named in the specification
- Share the asbestos register for older buildings

Advice
How the quote is worked out
Quotes vary with the job. It mainly depends on:
- Location, for remote and island sites
- The product specified
- Whether old sealant has to be cut out first
- Any access equipment needed
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
What we need to price the job
However big the job, these details speed things up:
- Asbestos survey details if the building is older
- The postcode of the building
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, speak to us on 01277 525 020 or use the quote form.
Your questions answered
Will you work in a care home in Kidbrooke without moving residents out?
Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.
Do you work for managing agents with blocks near Kidbrooke station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Is Kidbrooke in your area?
Yes. Kidbrooke falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or email the details over.
For managing agents and facilities managers
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
