Expansion joint sealing for commercial buildings in Walter's Ash
We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it, and we’ll confirm the choice in the quote. Most enquiries involve weathered movement joint sealant that no longer flexes and rain penetration at brick or block movement joints, on car park decks and ramps, podiums and floor movement joints and precast concrete panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Walter's Ash, that means joint design, primers and backing rod as standard.
For a site near Walter's Ash, measurements and photographs up front mean one trip where possible. Note joint widths and the traffic that uses them, and we will take it from there.
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.

Why deal with it now?
Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too and repeated access costs add up. We can price a patch and a full reseal side by side. One visit to deal with every failing joint makes more sense than several trips to a place like Walter's Ash, rather than one at a time. Photos of every joint help us quote for the whole job.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Warehouse floors and decks around Walter's Ash
Central London is about 32 miles from Walter's Ash. The South East has large numbers of industrial estates and warehouses along the motorway corridors. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint.
Schools such as Naphill and Walters Ash School have movement joints in their walls and floors that are easy to overlook. At places like Desborough Industrial Park, 2.8 miles south of Walter's Ash, joints are sealed a section at a time so operations carry on.

Your questions answered
Is Walter's Ash too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work at a site such as Crownfield Industrial Estate, by Walter's Ash?
Yes. Our area takes in Walter's Ash and its surroundings, with estates and business parks such as Crownfield Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
What happens if it rains on the day?
Weather matters for any external joint. Internal floor joints are far less affected.
How long does movement joint sealing take?
It normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, with phasing where areas must stay open. We will confirm when each area can be used again.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Related advice
Different surfaces, different methods
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. The product must bond to both substrates and cope with the movement priming where the maker calls for it.
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
What we can’t put right
Being straight saves everyone time. Fresh joints won’t solve:
- Movement on a scale no sealant is meant to absorb
- A joint that has to be widened or re-detailed before it can work
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If in doubt, call the office on 01277 525 020 or send photos by email and we will say what we think.

What we’re called out for in Walter's Ash
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.
Common reasons buildings call us in:
- Car park joints leaking onto vehicles below
- Arrises breaking up along floor joints
- Water getting into the wall through a failed joint
- Expansion joints filled with dirt and stones
A healthcare site such as Wycombe Hospital (3.7 miles south-east of Walter's Ash) depends on car parks, ramps and service yards whose joints take traffic all day.
