Owners, agents and contractors
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.
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Sudbury Hill can sit alongside others in a wider programme across Greater London.
How we handle expansion joint sealing in Sudbury Hill
Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed, and the sealant in them keeps water and debris out. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. If you are dealing with car park joints leaking onto vehicles below and arrises breaking up along floor joints, we can put it right, whatever the surface. Looking for mastic applicators who cover Sudbury Hill? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in Sudbury Hill means thinking about access, loading times and the ULEZ as well as the joints.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. 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.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Each joint is inspected and handed over with our 12-month guarantee.
Getting the site ready
- Share the asbestos register for older buildings
- Tell us which areas need to stay in use

Questions we are asked in Sudbury Hill
Is hospital work, at somewhere like The Clementine Churchill Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Is Greenford Green Business Park, near Sudbury Hill, within your area?
Yes, sites like Greenford Green Business Park are within our area, along with the rest of Sudbury Hill. Photos and a short description are enough for a first look.
Do you offer coloured sealant?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
What if the joint edges are damaged?
Sound edges are essential. Where they’ve broken up, we’ll tell you they need repairing first so you’re not paying for a bead that won’t hold.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or use the quote form. Photos, drawings or a joint schedule help us quote quickly.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What affects the price in Sudbury Hill
These are the things that shape the price:
- Removal of failed or old sealant
- The total length or number of joints
- Any access equipment needed
- Travel to remote or island sites
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- Specification clauses that apply
- How the joints are reached, and at what height
- The postcode of the building
- The type of building and who uses it
For a fixed quote, ring 01277 525 020 or email us, telling us the site location and the nature of the job. Our quote form is another easy route.
Do you need expansion joint sealing in Sudbury Hill?
Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.
Look out for the following:
- Rain penetration at brick or block movement joints
- Torn sealant in brick or block movement joints
- Joints where the bead has lost adhesion
- Expansion joints filled with dirt and stones
Another example is Phoenix Trading Estate, which lies south-east of Sudbury Hill, where floors and yards would be done in stages around the occupiers.

What else we do in Sudbury Hill
What we can’t put right
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Changing the joint layout or spacing of a structure
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Movement on a scale no sealant is meant to absorb
If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think before you book.
What we seal
- Podiums and floor movement joints
- Precast concrete panel joints
- Brickwork movement joints
- Blockwork control joints
- Cladding panel joints
- Car park decks and ramps
Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Note which joints were done, when, and with what
- Clear dirt from joint lines during routine cleaning
- Brief car park operatives to protect joint lines during winter clearance
- Report split or peeling joint sealant early
Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers. Sealing early protects the edges.
