About our external mastic in Fairlop

For buildings in Fairlop, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you are dealing with plants rooting in failed movement joints and movement joints filled with mortar instead of sealant, we can help. Whether you’re looking for a mastic man, a sealant applicator or a sealant company in Fairlop, Mr Mastic can help.

London’s terraces and conversions often share walls, gutters and downpipes with their neighbours, so a leaking gutter joint or failed wall joint can affect more than one home. In a converted house in Fairlop, it’s worth checking who is responsible for the outside before booking.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

What sealant work can’t fix

We won’t take on work that will not last, so here’s what sealant cannot put right:

  • Subsidence or other structural problems
  • Cracking across the wall rather than at a joint
  • Adding movement joints to masonry that has none

If you’re not sure, just call 07833 053749 or email us and we will give you a straight answer.

Where we work in Fairlop

What external mastic looks like in Fairlop

In terraces and conversions, gutters and walls are often shared with the neighbours, so it’s worth agreeing who is responsible before work starts. Historic houses like Valentines Mansion (about 2.1 miles south) are a reminder that the area around Fairlop has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.

Letting a property close to Seven Kings station? Then outside joints that have cracked can let damp into a rental, so check them between lets. As a London address, Fairlop can be tricky for parking: let us know about parking bays, permits or a driveway.

FAQs for Fairlop

Do you work for landlords with property near Seven Kings station?

Yes, rental work is part of what we do. You can ring 07833 053749 or email us with the address and a few details, and we will give you a fixed price before any work starts.

Can you do external mastic in Fairlop?

Yes, Fairlop is within the area we cover. Our work covers London and the South East. You can ring 07833 053749 or email us and let us know what needs doing, and we’ll give you a clear price.

Is it worth trying it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Can you seal joints between two different materials?

Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.

Where are you based?

We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Do I need to be at home?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

Is there a guarantee?

Yes, for a year. If there’s a problem with our work in that time, tell us and we will put it right.

Can you do several jobs on one visit?

Yes. More than one area can be quoted together.

DIY sealant or a professional job?

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

The process

On the day, we look over the joints with you first, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. The work usually takes anything from a few hours to several days, depending on the building. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  1. First, the joints are inspected and the access agreed.
  2. Every bit of old sealant and any mortar or debris is cut out.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. Backing rod sized to the joint goes in to set the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Preparing for the visit

  • Tell us about any water getting in
  • Try not to wet indoor joints just before the visit
  • Let us know about earlier repairs to the joints

Advice

Aftercare tips

How long the joints last depends on use and care. Here’s what we suggest:

  • Keep soil, plants and ivy away from the joints
  • Fix overflowing gutters above sealed joints
  • Have failed joints looked at early
  • Point out the joints to other trades

Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.

A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Catch it early and you reduce the risk.

What we’re called out for in Fairlop

Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.

Keep an eye out for any of the following:

  • Gaps where render, brick and frames meet
  • Brick movement joints where the sealant has split
  • Joints pointed up with cement by mistake
  • Leaking joints around cladding and façade panels

Managing a site like Fairlop Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

  • Is VAT in the price?
