Expansion joint sealing for Well Hill sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What happens if it’s left?
A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed. For buildings around smaller places like Well Hill, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

About our expansion joint sealing in Well Hill
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. Site teams most often ask us about water dripping through deck or ramp joints and spalled or broken joint edges in floors and decks, across blockwork control joints, brickwork 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 Well Hill, that means joint design, primers and backing rod as standard.
For a site near Well Hill, 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.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What the job involves on each surface
Podium joints
Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.
Joints between different materials
Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement priming where the maker calls for it.
Quoting for work in Well Hill
To price the job, we consider:
- Specialist products, such as fire-rated or hygienic sealants
- Site requirements such as inductions and permits
- Joint width, depth and condition
- The total length or number of joints
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
Details that help us quote
The more we know, the firmer the quote. When you get in touch, include:
- The product your specification calls for
- Clear photos of the problem areas
- The asbestos register, for older buildings
- Approximate linear metres or a joint schedule
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or send photos by email.

- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Common questions from Well Hill clients
Can you work on a hospital site such as Chelsfield Park Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Is Well Hill too small for you to travel to?
No. Small places get the same service as large ones. We cover Greater London and the counties of 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.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Can you seal joints in cold or wet weather?
Outside work depends on conditions: rain, frost and condensation all stop sealant bonding. Indoor joints can typically carry on regardless.
How long will the joint resealing take?
That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member.
On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Rural sites near Well Hill may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- 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
- For older buildings, check the asbestos register before work
- Send your site hours and access windows
- Warn occupants and staff about the work
Request a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Related advice
After the work
A few simple habits keep the new joints working:
- Plan racking layouts so feet don’t land on a joint
- Inspect movement joints alongside other routine building checks
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Record the sealant used and the date in the O&M file
Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth. Barriers left in place until then protect the finish.
Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load. A sound seal keeps the joint working.
