Common problems we fix in Holmer Green
Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.
Any of the following is a good reason to get the joints checked over:
- Rain penetration at brick or block movement joints
- Leaks through car park deck joints onto the level below
- Hardened, cracked sealant on exposed facades
- Expansion joints filled with dirt and stones
For estates staff at a university like Buckinghamshire New University, 2.5 miles to the north-east of Holmer Green, building and paving joints are part of the planned maintenance list.
Questions to ask before you book
- Whether old or failed sealant will be cut out, not overlaid
- Their pre-qualification and accreditations
- How they’ll work around occupants
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Expansion joint sealing in Holmer Green, done properly
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, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. We work on brickwork movement joints, cladding panel joints and blockwork control joints, and what we’re called in for most is movement joints with split or torn sealant and sealant peeling off one face of the joint. Whether you call it commercial sealant work, mastic application or joint sealing, in Holmer Green it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around places the size of Holmer Green, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Diagnose, treat, sign off
Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a job in Holmer Green, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.
- 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.
- The failed seal is removed and both faces are cleaned until sound and dry.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Preparing the site
- For older buildings, check the asbestos register before work
- Warn occupants and staff about the work
- Agree which areas must stay open

Surface by surface
Car park decks and ramps
Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond, so the new seal holds.
Why deal with it now?
Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed and we’ll tell you honestly. In a smaller place such as Holmer Green, 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.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Keep product details with the building records for the next reseal
- Put movement joints on the planned maintenance inspection round
- Clear dirt from joint lines during routine cleaning
- Report split or peeling joint sealant early
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in and long before edges start to break. If anything looks wrong, speak to us on 01277 525 020 or email drawings and photos with photographs.
Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.

Questions we’re asked in Holmer Green
Is Holmer Green too far out for you?
No. Places such as Holmer Green are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Will our site in Holmer Green have to close for joint sealing?
In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
What happens if it rains on the day?
Sealing onto a damp surface leads to adhesion failure, so external work waits for suitable conditions. We agree a revised date with you.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
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.
How do we ask for a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.
