About our expansion joint sealing in Broomhall
Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. Site teams most often ask us about water getting into the wall through a failed joint and car park joints leaking onto vehicles below, on blockwork control joints, precast concrete panel joints and brickwork movement joints. Most enquiries from Broomhall start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Small units near places like Broomhall are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Surface by surface
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen, and we will confirm the colours available for the specified product.
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.

Why act early in Broomhall
Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly. We cut out the old seal and prepare the faces every time. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you’re ready.

Joints that move: notes for Broomhall
Central London is about 24 miles from Broomhall. Warehousing clusters around the motorways that ring and radiate from London. Broomhall sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.
Schools like Sunningdale School often have long brick elevations with movement joints that age quietly. Large sites such as Heatherwood Hospital (2.6 miles north-west of Broomhall) have car parks, service roads and long elevations with movement joints in brick and panels.
Broomhall is about 4 miles south-west of Egham, in Windsor and Maidenhead. We send applicators to Broomhall for movement joints, handled exactly as we handle every other area. Across Windsor and Maidenhead, 60 places are covered, Broomhall among them. There’s a separate page for Reading, roughly 15 miles from Broomhall.

Maintenance after handover
A few simple habits keep the new joints working:
- Treat a small split as a warning, not a cosmetic issue
- Include every elevation and deck joint in periodic inspections
- Avoid parking heavy plant or pallets on joint lines
- Note which joints were done, when, and with what
Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it. Regular sweeping keeps joint lines clear.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Catching it early keeps the water outside.
Signs you need expansion joint sealing in Broomhall
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.
Any of the following is a good reason to get the joints checked over:
- Torn sealant in brick or block movement joints
- Previous reseals laid over old sealant
- Brittle, chalky sealant on external joints
- Spalled or broken joint edges in floors and decks
For estates staff at a university like Imperial College Silwood Park Campus, 1.5 miles to the north-west of Broomhall, building and paving joints are part of the planned maintenance list.

Diagnose, treat, sign off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. What matters most for a job in Broomhall is a clear list of what needs doing. A fixed quote follows.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- 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
- Agree which areas must stay open
- Point out parking and an unloading spot

FAQs: Broomhall
Is Broomhall too far out for you?
No. Places such as Broomhall are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Can you take on a job at a hospital such as Heatherwood Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
What do you charge?
Every job gets its own fixed quote. To get one, speak to us on 01277 525 020 or email the details over.
How do I request a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Will you come and look before quoting?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit before quoting.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
