Expansion joint sealing for commercial buildings in Woodside
Mastic Doctor has sealed movement joints since 2005. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on precast concrete panel joints, brickwork movement joints and blockwork control joints, and the usual reasons a site gets in touch are joints where the bead has lost adhesion and layers of sealant in a movement joint. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Woodside, preparation and product choice get the time they need.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Woodside, as everywhere in London, access, loading and the ULEZ all come into the plan.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

On site: what to expect
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a job in Woodside, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Agree which areas must stay open
- Send your site hours and access windows

Expansion joint sealing in Woodside: the local picture
Less than 3 miles from Woodside 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. London car parks, loading bays and podium decks often can’t close for long, so joints are sealed in sections with each area handed back once cured.
On a site such as Chaffinch Business Park (1 mile north-east of Woodside), the movement joints are in car park slabs, paving and building elevations. At a retail site such as Whitgift Centre (1.7 miles south-west of Woodside), trolleys, cages and cars run over floor and slab joints all day.

Your questions answered
Can you take on a job at a hospital such as Shirley Oaks Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Will you take on work at estates like Chaffinch Business Park, close to Woodside?
Yes, sites like Chaffinch Business Park are within our area, along with the rest of Woodside. Photos and a short description are enough for a first look.
Do you cover Woodside?
Yes. We cover Woodside and the rest of Greater London, within our coverage of Greater London, South East England and Scotland. To discuss a job, call 01277 525 020 or send details through our quote form.
Is colour matching possible?
It depends on the product specified. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Surface by surface
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.
What we’re called out for in Woodside
The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.
It’s worth sending us details if you spot any of the following:
- Spalled or broken joint edges in floors and decks
- Sealant peeling off one face of the joint
- Expansion joints split through the centre of the bead
- Debris jammed in movement joints
Another example is Franklin Industrial Estate, 1.8 miles north of Woodside, where floors and yards would be done in stages around the occupiers.
Comparing quotes
- Will RAMS and insurance details be available?
- Is the sealant right for the movement and the substrate?
- How the joint faces will be prepared and primed
- Will CSCS-carded applicators be on site?
Cost factors for movement joints
Your fixed quote is built from the real scope. It takes account of:
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
- Working within restricted access windows
- Whether old sealant has to be cut out first
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- The asbestos register, for older buildings
- Where the site is, with the postcode
- Specification clauses that apply
- Rough lengths or quantities, or drawings if you have them
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to give us a call on 01277 525 020 or send details through our quote form.
Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Woodside can form part of a wider programme.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
When something else is needed
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Crumbling edges that would give a new bead nothing sound to grip
- Damaged metal nosings or cover plates over a joint
- Waterproofing layers buried beneath the sealant
If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
