Photos, a specification or a quick description of the joints is enough to start a fixed quote.
After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Include every elevation and deck joint in periodic inspections
- Check joints after long freezing spells
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Record the sealant used and the date in the O&M file
Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check and long before edges start to break. If anything looks wrong, call 01277 525 020 or email the details over with photos.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Sealing early protects the edges.

Questions we’re asked in Bishop's Waltham
Is a smaller place like Bishop's Waltham outside your area?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Is hospital work, at somewhere like Moorgreen Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
How long will the joint resealing take?
It usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Timings are set out in the quote, including any phasing.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Do you guarantee expansion joint work?
Our workmanship on movement joints carries a 12-month guarantee. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.
Which product is best for expansion joints?
Movement capability matters most as set out in BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.
When to bring in a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Our process
Diagnose, treat, sign off: every visit follows that pattern. 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 Bishop's Waltham 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.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Agree which areas must stay open
- Warn occupants and staff about the work
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.
Advice
Leave it or put it right?
A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we will tell you honestly. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.
What you get with us
- Coloured sealants to suit the setting, where available
- CHAS accredited
- 12-month guarantee on workmanship
- Commercial sealant work since 2005
What affects the price in Bishop's Waltham
Before we quote, we look at:
- Site requirements such as inductions and permits
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
- The total length or number of joints
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.
Sending details for a quote
We can often quote from photographs and a few details. Please tell us:
- Asbestos survey details if the building is older
- The type of building and who uses it
- The postcode of the building
- Access details, including height
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- A joint that has to be widened or re-detailed before it can work
- Leaks coming from the membrane rather than the joint seal
Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we will tell you honestly.
