Expansion joint sealing in Walham Green, done properly
For movement joints in Walham Green, photographs and approximate lengths are the best start. Send them through our quote form, and we’ll arrange a site visit if needed before issuing a fixed quote. To discuss the joints first, give us a call on 01277 525 020 or email a schedule or drawings. If you have weathered movement joint sealant that no longer flexes and sealant peeling off one face of the joint, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Walham Green is the same: the right product in a properly prepared joint.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Questions we’re asked in Walham Green
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
Can you take on a job at a hospital such as Chelsea and Westminster Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Are you fully insured?
Yes. We are fully insured, and the certificate can go with your quote.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
What hours do you work?
We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- First the joints are inspected, widths measured and the type of failure noted.
- 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.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Point out any areas we must not close
- Let building users know which areas are affected
- Point out parking and an unloading spot
Quotes
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Building owners, agents and FMs in Walham Green
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Walham Green can form part of a wider programme.
Signs you need expansion joint sealing in Walham Green
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears.
These are often picked up first by site or facilities staff:
- Torn sealant in brick or block movement joints
- Weathered movement joint sealant that no longer flexes
- Leaks through car park deck joints onto the level below
- Previous reseals laid over old sealant
A campus such as BIMM University (under half a mile west of Walham Green) has long runs of movement joint in its buildings, decks and paving.
What to look for in a quote
- Will CSCS-carded applicators be on site?
- How joint depth will be controlled
- Is the sealant right for the movement and the substrate?
- What site paperwork they can supply

Surface by surface
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.
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen in a colour confirmed for that product.
What happens if it’s left?
On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open. Tell us what has to stay open and we will plan around it. In Walham Green, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
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’ll explain how it’s made up.
What you get with us
- Workmanship guaranteed for 12 months

- 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)
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
