Expansion joint sealing in Garston, done properly
We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it. If you have movement joints with split or torn sealant and arrises breaking up along floor joints, we can help, on precast concrete panel joints, blockwork control joints and car park decks and ramps alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Garston it comes down to the same thing: the right product in a properly prepared joint.
In a smaller place such as Garston, 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.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When something else is needed
Some faults sit outside our scope, and we say so rather than covering them up:
- A joint that has to be widened or re-detailed before it can work
- Crumbling edges that would give a new bead nothing sound to grip
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think.

Other services in Garston
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Common problems we fix in Garston
Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch.
Typical triggers for a call:
- Leaks through car park deck joints onto the level below
- Rain penetration at brick or block movement joints
- Weathered movement joint sealant that no longer flexes
- Movement joints with split or torn sealant
If you manage units on an estate such as Colne Way Industrial Estate (0.5 miles south of Garston), the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.
What to look for in a quote
- The named product and why it was chosen

- Whether their applicators hold CSCS cards
Looking after the joints
A few simple habits keep the new joints working:
- Avoid parking heavy plant or pallets on joint lines
- Look over external and deck joints after a hard winter
- Put movement joints on the planned maintenance inspection round
- Keep stones and debris out of open joint lines
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records so future maintenance isn’t guesswork.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We can suggest an order, worst joints first.

Your questions answered
Would you work within a site like Watford General Hospital?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Is a smaller place like Garston outside your area?
No. Places such as Garston are covered as much as the big towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Can you seal joints in cold or wet weather?
A wet joint can’t be sealed properly. We agree a revised date with you.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
What will the job cost?
We don’t publish prices, because every site is different. Send photos or drawings and we’ll price it at a fixed figure.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Do you have public liability insurance?
Yes. We are fully insured, and the certificate can go with your quote.
Our process
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Work in places the size of Garston is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Share your working hours and any access restrictions
- Send asbestos survey details if the building is pre-2000
- Make sure the joints can be reached
