About our expansion joint sealing in Honor Oak
We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it. The enquiries we see most involve joints where the bead has lost adhesion and debris jammed in movement joints, on brickwork movement joints, podiums and floor movement joints and cladding panel joints. Searching for sealant specialists in Honor Oak? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up, so it pays to act early.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Site staff or a sealant specialist?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

What happens if it’s left?
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
What you get with us
- Public liability insurance in place
- Specification-led, product-correct work
- Joints cleaned back to sound surfaces
- Matching to RAL references, product permitting

What affects the price in Honor Oak
There’s no standard rate for sealant work, because every site is different. What we look at:
- Backing rod, priming and other preparation
- Whether the work must be split into stages
- Whether old sealant has to be cut out first
- Quantities, in metres or numbers
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.
Details that help us quote
Diagnosis starts before we arrive. Tell us:
- Access details, including height
- Specification clauses that apply
- The type of building and who uses it
- Your programme or deadline
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email drawings and photos.
Common questions from Honor Oak clients
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Can you work at a site such as Clyde Vale Industrial Estate, by Honor Oak?
Yes. We cover Honor Oak and the area around it, including industrial estates, business parks and retail parks such as Clyde Vale Industrial Estate. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can a joint be sealed if the edges are broken?
The edges have to be sound. Where they’ve broken up, we will tell you they need repairing first, so the new seal has something to grip.
What sealant do you use in movement joints?
Whatever suits the joint and the specification. The quote states the sealant and its movement class.
Is movement joint sealing guaranteed?
A 12-month guarantee covers our workmanship, and we’re fully insured for public liability. Keeping joints clear of debris helps them last.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. All of Greater London is in the ULEZ, and kerbside space in Honor Oak can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- Confirm the product named in the specification
- Tell us which areas need to stay in use
- Move anything stored against the joints

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photographs and a description will do.

For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Honor Oak can form part of a wider programme.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Joints that move: notes for Honor Oak
In London, decks, bays and service yards usually have to keep running, so joints are sealed in sections with each area handed back once cured. Less than 3 miles from Honor Oak there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
Phasing is what makes joint work possible on busy sites such as Goose Green Trading Estate (1.1 miles north-west of Honor Oak): one bay, aisle or car park row at a time. Estates like Clyde Vale Industrial Estate, 1 mile south of Honor Oak, combine warehouse slabs, yards and loading bays, all with joints under wheels. For estates staff at a university like King's College London, 2.2 miles to the north-west of Honor Oak, building and paving joints are part of the planned maintenance list.

When it isn’t the sealant

- Proprietary pre-formed expansion joint systems
- A joint that has to be widened or re-detailed before it can work
