How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. All of Greater London is in the ULEZ, and kerbside space in North Brixton can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

- We take off quantities and return a fixed quote.
- The sequence is agreed with the site manager.
- Each area is sealed when it’s released.
- Joints are prepared, backed and sealed to the specification.
- After snagging, the work is handed over under our 12-month guarantee.
What we need from you

How we handle construction mastic in North Brixton
External mastic depends on the weather in a way most internal trades don’t. Each sealant has a temperature range, and damp, frost or condensation on frames stops work, so we plan elevations with the forecast and the programme in mind. Internal areas can usually carry on while the outside waits. Site teams most often ask us about sanitary sealant damaged by following trades and frame gaps too wide for sealant alone, on brick and block movement joints, internal decorators’ caulk and cladding and panel joints. Looking for mastic applicators who cover North Brixton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

For managing agents and facilities managers
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
What we are called out for in North Brixton
A joint without backing rod or bond-breaker often fails early. Fixed to three faces, the sealant rips the first time the joint opens so we set the depth properly before sealing.
These are often picked up first by site or facilities staff:
- Perimeter gaps outside the sealant’s range
- A mastic package split between trades with no clear owner
- Old sealant on a refurbishment that needs stripping before new work
- Internal caulk splitting as the building dries out
New wings at hospitals like Lambeth Hospital (0.7 miles south-west of North Brixton) bring long runs of window and panel joints to seal.

What else we do in North Brixton
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
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.
After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Bring the mastic contractor in after the last trades are through
- Allow flexibility for external sealing in damp or cold weather
- Stick to the specified sealant rather than a generic substitute
- Check frame gaps are within the sealant’s range before sealing
Any damage after we have finished should go on the snag list straight away. Snags can be picked up in a planned close-out visit as agreed in the quote.
External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks.

North Brixton: questions and answers
Will you plan work around the academic year at somewhere like King's College London?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
What do you charge?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we will price it properly.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Do you take on mastic snagging only?
Yes. Snag-only work is something we take on and damaged joints are redone properly.
Does weather affect external mastic work?
Outside, the joint has to be dry and the temperature within the product’s limits. Frosty or damp mornings can hold up external sealing so we typically switch to internal work when that happens.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
Why deal with it now?
Sealing over damaged or contaminated new joints might save a day, but it won’t last. Sealant can’t grip a contaminated or existing bead and the defect reappears in the defects period. Damaged joints are removed and resealed from clean faces. Getting scaffold, permits or access booked in North Brixton takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
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?
- Old sealant cut out, never sealed over
- One number for every site we cover
- Fully insured
- Work carried out by CSCS-carded applicators
