Questions we’re asked in Green End
Is a smaller place like Green End outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can you work at a site such as Crownfield Industrial Estate, by Green End?
Yes. Estates, retail parks and business parks around Green End, Crownfield Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Will you just go over the old sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.
Can a joint be sealed if the edges are broken?
Broken arrises have to be put right before resealing. Sealing over them leads to early failure.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Expansion joint sealing for commercial buildings in Green End
The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you are dealing with brittle, chalky sealant on external joints and joints where the bead has lost adhesion, we can put it right. A single leaking joint is often how a building in Green End first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
In and around smaller places like Green End, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Leaks coming from the membrane rather than the joint seal
- A joint that has to be widened or re-detailed before it can work
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If you’re not sure, just call the office on 01277 525 020 or use the quote form and we’ll give you a straight answer.

Building owners, agents and FMs in Green End
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.
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
Different surfaces, different methods
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them.
Brickwork and blockwork joints
Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, usually low-modulus.

Advice
What we are called out for in Green End
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens.
Common reasons buildings call us in:
- Movement joints with split or torn sealant
- Debris jammed in movement joints
- Water getting into the wall through a failed joint
- Weathered movement joint sealant that no longer flexes
Schools like The Mary Towerton School At Studley Green often have long brick elevations with movement joints that age quietly.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint
- Will RAMS and insurance details be available?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the existing material will be dealt with

After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Inspect exposed joints once the cold weather has passed
- Keep product details with the building records for the next reseal
- Reopen bays and walkways only after the stated cure time
- Keep stones and debris out of open joint lines
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint and we’ll tell you when each bay or area can reopen. Keeping the area coned off until then avoids tyre marks and damage.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Resealing promptly prevents internal damage.
