Expansion joint sealing for commercial buildings in Washington
The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on car park decks and ramps, blockwork control joints and brickwork movement joints, and the failures we’re asked to look at most are sealant pulling off the joint face and joints packed with grit and debris. Whoever orders the work in Washington, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places such as Washington, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Maintenance after handover
Once the work is signed off, these steps help:
- Note which joints were done, when, and with what
- Inspect movement joints alongside other routine building checks
- Keep scrapers and ploughs from dragging across joint sealant
- Act on the first tear or lifting edge rather than waiting
Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster. Keeping the filler or sealant sound protects the floor.

For managing agents and facilities managers
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.
Cost factors for movement joints
We price every job individually. The main factors are:
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
- Any access equipment needed
- The site’s rules and procedures
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
We can often quote from photographs and a few details. It helps to include:
- The asbestos register, for older buildings
- Anything awkward about access or site hours
- What the building is and how it’s used
- Any dates the work must fit around
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Your questions answered
Will you take on work at estates like Rock Business Park, close to Washington?
Yes. Our area takes in Washington and its surroundings, with estates and business parks such as Rock Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Is Washington off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
What do you charge?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
What if the joint edges are damaged?
Sound edges are essential. Where they’ve broken up, we will tell you they need repairing first.
Is colour matching possible?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Different surfaces, different methods
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix.
Where floor joints take the most wear near Washington
Washington is in the South East, one of the UK’s drier regions. 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. At about 43 miles from central London, Washington is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day.
Another example is Wiston Business Park, 1.2 miles to the north of Washington, where floors and yards would be done in stages around the occupiers. For buildings at a park such as Rock Business Park (0.7 miles north-east of Washington), brick and panel movement joints are easy to forget until one leaks.
Washington is about 6 miles north of Worthing, in West Sussex. Looking for expansion joint sealing in Washington? We can help, as we do across West Sussex. Across West Sussex, 373 places are covered, Washington among them. For work in that direction, see our Brighton page, about 13 miles away.

When to call us in Washington
Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch.
Common reasons buildings call us in:
- Car park joints leaking onto vehicles below
- Torn sealant in brick or block movement joints
- Spalled or broken joint edges in floors and decks
- Joints where the bead has lost adhesion
In a school such as St Mary's CofE Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Our process
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Washington, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- We strip out the old seal and prepare the faces.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Before we start on site
- Point out parking and an unloading spot
- Flag any permit to work we will need
- Tell us which areas need to stay in use
