About our mastic sealing in The Burroughs
We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. 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 estate-wide sealant that is simply worn out and open joints in brickwork or panels, on communal entrances and stairwells, window and door perimeters on blocks and balcony and threshold joints. Most enquiries from The Burroughs start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
London has a large stock of purpose-built blocks, mansion flats and converted buildings managed by agents and housing associations. Mastic around windows, doors and balconies tends to fail across a whole block at a similar time.
A 12-month guarantee applies to all our work. If an installation problem shows up, ring 01277 525 020 or send photos by email and we’ll arrange a return visit.

Planned mastic for The Burroughs portfolios
For a London block, the agent or landlord normally handles notices to residents and access to flats. We plan around the notices and access you arrange. The Burroughs has four care or nursing homes no more than 2 miles away. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.
For a school such as St Joseph's Catholic Primary School, perimeter mastic on windows and doors is a holiday job. Trustees of buildings like St Mary's Church can bring frame and external mastic into a planned maintenance list.
The Burroughs is about 2 miles south-east of Burnt Oak, in Greater London. Our applicators travel to The Burroughs for work on mastic joints. Across Greater London, 764 places are covered, The Burroughs among them. London is covered too, some 8 miles away.
Commercial sites across NW4, NW9 and NW11 are covered for mastic joints. If your site is on Bell Lane, Eaton Road and Lodge Road or close by, send details and we’ll quote for mastic joints. Access to The Burroughs is via the A41 among other routes, so getting applicators and materials to site is simple. We also cover Hendon (1 mile south-east), Colindale (1 mile west), Brent Cross (1 mile south-east), West Hendon (1 mile south-west) and The Hyde (1 mile south-west). Bigger towns within reach include London (8 miles south-east), City of Westminster (6 miles south-east), Marylebone (6 miles south-east), Kensington (6 miles south), St Pancras (6 miles south-east) and Shoreditch (8 miles south-east).
Near you in The Burroughs
We work on buildings around The Claddagh Ring pub, Brampton College and Kisharon College. The Burroughs’s nearest station is Hendon station, roughly 0.8 miles south-west of the centre.

What we are called out for in The Burroughs
Occasionally the substrate fails, not the sealant for instance where render or brick edges crumble. We will tell you if the joint edges need repairing before resealing.
Any of the following is a good reason to get the joints checked over:
- Leaks at window and door perimeters
- Draught complaints from residents or tenants
- Repeated reactive repairs to the same buildings
- Estate-wide sealant that is simply worn out
If you own or manage units on a site such as Silk Bridge Retail Park, 0.9 miles south-west of The Burroughs, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- Will RAMS and insurance details be available?
- Will failed sealant be removed rather than covered?
- Proof of insurance
What sets the cost
Your fixed quote is built from the real scope. It allows for:
- Quantities, in metres or numbers
- Distance, for remote addresses
- The size and state of each joint
- Removal of failed or old sealant
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
Details that help us quote
A few photographs plus some basic facts will normally do. Please tell us:
- Any specification or named product
- Anything awkward about access or site hours
- Any dates the work must fit around
- Where the site is, with the postcode
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email a schedule or drawings to discuss it first.
When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What the job involves on each surface
External movement joints
Brickwork, blockwork and panel joints let a building move. Failed sealant in a movement joint lets water in.
Communal areas
Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Fresh joints make shared areas look looked after.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Share your contractor requirements early
- Reduce knocks to communal area joints
- Share the asbestos register when you send details
- Encourage occupiers to report problems at frames
Encourage occupiers to report water or draughts at frames. Early reports catch failures before damage spreads.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.
The Burroughs: questions and answers
Can you quote for a block close to Hendon station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Is Silk Bridge Retail Park, near The Burroughs, within your area?
Yes. Estates, retail parks and business parks around The Burroughs, Silk Bridge Retail Park among them, are all within reach. Photos and a short description are enough for a first look.
Is The Burroughs in your area?
Yes. The Burroughs falls within our area, and the simplest way to start is to call the office on 01277 525 020 or email a schedule or drawings.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
How do you reach windows on upper floors?
It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.
How long does a job like this take?
That varies with the scale of the job, though a typical visit usually takes a day or two for a single block, longer for an estate programme. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
