We work on brickwork movement joints, precast concrete panel joints and cladding panel joints, and the failures we are asked to look at most are new sealant over old, now failing and arrises breaking up along floor joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Ellen's Green is the same: the right product in a properly prepared joint.
For a site near Ellen's Green, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.
Every job we finish is backed by a 12-month workmanship guarantee, in Ellen's Green as everywhere else we work. If our installation lets you down in that time, we return and fix it.

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.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
On site: what to expect
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically 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, and our waste is bagged and taken away as we go. For a building around Ellen's Green, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Agree which areas must stay open
- Confirm the product named in the specification
- Share the asbestos register for older buildings

Why it’s worth doing now in Ellen's Green
Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use without shutting the whole car park. We agree phasing with you before work starts. One visit to deal with every failing joint makes more sense than several trips to a place like Ellen's Green. Send photos of each area and we will quote for the lot.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Questions we’re asked in Ellen's Green
Is Ellen's Green off your patch?
No. Places such as Ellen's Green are covered as much as the big towns. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.
Can you work on a hospital site such as Horsham Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards.
Are you fully insured?
Yes. Our insurance certificate can be sent alongside the quote.
Which product is best for expansion joints?
It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints, and the specification has the final say.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
What the job involves on each surface
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.
Traffic, movement and joints around Ellen's Green
At about 30 miles from central London, Ellen's Green is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.
If you manage units on an estate such as The Old Brickworks Industrial Estate, which lies south-west of Ellen's Green, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. At places like Northlands Business Park (2.1 miles east of Ellen's Green), joints are sealed a section at a time so operations carry on. Hospitals like Horsham Hospital (to the south-east of Ellen's Green) have multi-storey or surface car parks whose joints carry vehicles round the clock.
Ellen's Green is about 5 miles north-west of Horsham, in Surrey. Any commercial site in Ellen's Green is covered, whether it’s a single job or part of a planned programme.

Quoting for work in Ellen's Green
We price every job individually. The main factors are:
- The size and state of each joint
- Site requirements such as inductions and permits
- Phasing around occupants
- How much existing material needs removing
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
Details that help us quote
We can often quote from photographs and a few details. Please tell us:
- Rough lengths or quantities, or drawings if you have them
- What the building is and how it’s used
- Any dates the work must fit around
- The site address and postcode
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email us.
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be one of these:
- Joints too narrow for the movement, which need redesigning by the engineer
- Crumbling edges that would give a new bead nothing sound to grip
- Damaged metal nosings or cover plates over a joint
If in doubt, speak to us on 01277 525 020 or email us and we’ll say what we think before you book.
