Expansion joint sealing for Holloway sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Rural sites near Holloway may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- 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.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Tell us your opening times and when work is allowed
- Make sure the joints can be reached
- Confirm the product named in the specification
Ask for a quote
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

About our expansion joint sealing in Holloway
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels so the product has to suit both the traffic and the movement. If the arrises are already broken, we’ll say so before sealing and phasing can keep areas working. Most enquiries involve hardened, cracked sealant on exposed facades and joints where the bead has lost adhesion, across podiums and floor movement joints, brickwork movement joints and precast concrete panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Holloway, that means joint design, primers and backing rod as standard.
Jobs around smaller places like Holloway are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

How the job changes by surface
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Close-up photos help us judge the joints, or we visit if they don’t show enough.
Honest limits
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:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Concrete or masonry repairs along the arrises
- Leaks coming from the membrane rather than the joint seal
If you’re not sure, just call the office on 01277 525 020 or send photos by email and we will give you a straight answer.

Cost factors for movement joints
Quotes vary with the job. It mainly depends on:
- How much there is to seal
- Which sealant the job calls for
- How much existing material needs removing
- Joint width, depth and condition
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Asbestos survey details if the building is older
- Specification clauses that apply
- Any dates the work must fit around
- What the building is and how it’s used
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Keep racking legs and heavy point loads off floor joints
- Act on the first tear or lifting edge rather than waiting
- Keep stones and debris out of open joint lines
- Record the sealant used and the date in the O&M file
Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. If anything looks wrong, call the office on 01277 525 020 or email the details over with photographs.
Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one. We can suggest an order, worst joints first.
Holloway: questions and answers
Can you work at a site such as Maidenhead Business Park, by Holloway?
Yes, sites like Maidenhead Business Park are within our area, along with the rest of Holloway. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
Is Holloway off your patch?
Not at all. Holloway is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Can the sealant be colour-matched?
That depends on the product. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
What exactly is a movement joint?
It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing.
What guarantee do you give on joint sealing?
It’s backed by our 12-month guarantee. Tell us straight away if a joint we sealed gives trouble in that time.
Expansion joint sealing around Holloway: how the place shapes the job
Holloway lies roughly 30 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London. The 3 miles around Holloway take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
For a centre such as Cliveden View Shopping Centre (2.7 miles north-east of Holloway), the service yard and car park joints usually need attention first. Sites like St Mark's Hospital, 1.9 miles east of Holloway, carry ambulances, deliveries and visitors’ cars over their road and deck joints. At places like Rashleighs Business Centre, which lies north-east of Holloway, joints are sealed a section at a time so operations carry on.
Holloway is about 2 miles west of Maidenhead, in Windsor and Maidenhead. We cover commercial sites throughout Holloway, for single jobs and planned programmes alike.

Local landmarks in Holloway
Locally, jobs take us to sites close to The Shire Horse pub, Newlands Girls' School and Manor Green School and the streets around them.

Green spaces nearby include Taplow Lake and Weycock Hill.
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.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
