Why it’s worth doing now in North Lee
Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use. Tell us what has to stay open and we’ll plan around it. Converted and older buildings near places like North Lee tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Keep scrapers and ploughs from dragging across joint sealant
- Treat a small split as a warning, not a cosmetic issue
- Include every elevation and deck joint in periodic inspections
- Inspect exposed joints once the cold weather has passed
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. Should you spot a problem, you can give us a call on 01277 525 020 or send photos by email and send a picture.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors. Catching it early keeps the water outside.
When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

How a job runs
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around North Lee, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- 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.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Preparing the site
- Have the specification and drawings to hand
- Warn occupants and staff about the work
- Send asbestos survey details if the building is pre-2000

Advice
Common questions from North Lee clients
Is North Lee too small for you to travel to?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. 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 Weston Way Industrial Estate, by North Lee?
Yes, sites like Weston Way Industrial Estate are within our area, along with the rest of North Lee. A few photographs and the unit address let us price the work.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How much does the work cost?
Every job gets its own fixed quote. For yours, speak to us on 01277 525 020 or send photos by email.
What happens if it rains on the day?
A wet joint can’t be sealed properly, so external work waits for suitable conditions. The work is simply moved to the next suitable day.
What we’re called out for in North Lee
When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, usually means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way, so we check width and movement before quoting.
Typical triggers for a call:
- Debris jammed in movement joints
- Arrises breaking up along floor joints
- Water dripping through deck or ramp joints
- Sealant pulling off the joint face
University campuses such as University Campus Aylesbury Vale (2.8 miles north of North Lee) have car parks, paved walkways and building elevations with movement joints.
