Where floor joints take the most wear near Martins Heron
Martins Heron sits in or beside Bracknell, a twentieth-century planned town. With industry zoned from the outset, there’s a concentration of older warehouse floors whose joints take daily traffic, so a planned programme across a site can make sense. The 3 miles around Martins Heron 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.
University campuses such as Imperial College Silwood Park Campus, 3.3 miles east of Martins Heron, have car parks, paved walkways and building elevations with movement joints. For an estate such as Heatherwood Hospital, 1.6 miles east of Martins Heron, the joints in ramps, decks and long building elevations all need attention over time. Schools such as Harmans Water Primary School have movement joints in their walls and floors that are easy to overlook.

About our expansion joint sealing in Martins Heron
We have been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. 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 cladding panel joints, blockwork control joints and podiums and floor movement joints, and the failures we are asked to look at most are spalled or broken joint edges in floors and decks and water getting into the wall through a failed joint. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Martins Heron, preparation and product choice get the time they need.
In a smaller place such as Martins Heron, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Their slabs and walls still need movement joints that work.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Keep stones and debris out of open joint lines
- Keep racking legs and heavy point loads off floor joints
- Look over external and deck joints after a hard winter
- Include every elevation and deck joint in periodic inspections
Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.
On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. That water often carries de-icing salts with it and it can affect the structure over time. Sealing the joint promptly stops it at source.
FAQs: Martins Heron
Are the floor joints in an older unit in Bracknell worth resealing?
In the majority of cases it is, if the edges haven’t broken up too far. We will advise on the product for your traffic and flag any edges that need repair first.
Is a smaller place like Martins Heron outside your area?
Not at all. Martins Heron is within our area. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
How long does movement joint sealing take?
Allow a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Timings are set out in the quote, including any phasing.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Building owners, agents and FMs in Martins Heron
Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Why deal with it now?
Resealing is typically the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we will tell you they need repairing first. In a smaller place such as Martins Heron, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we’ll price your job on its own details.
What you get with us
- A fixed quote before work starts
- Specification-led, product-correct work
- Fully insured, including public liability cover
- A Constructionline member, so easy to vet
Honest limits
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Movement on a scale no sealant is meant to absorb
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- A joint that has to be widened or re-detailed before it can work
If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer.

Our process
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. What matters most for a job in Martins Heron is a clear list of what needs doing. You’ll then get a fixed price for the work.
- First, the joints are inspected for width, movement and the type of failure.
- 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, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.
Getting the site ready
- Let building users know which areas are affected
- Clear stock, furniture or equipment away from the joints
- Have the specification and drawings to hand
Getting a fixed quote
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, photographs and a description will do.

Different surfaces, different methods
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.
Joints between different materials
Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces.
