External mastic near Enfield Wash

About our external mastic in Enfield Wash

Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you have joints where the bead has come unstuck and cracked joints where brick meets render or frames, we can put it right, whatever the surface. Mr Mastic is a mastic company, not a general handyman, so external mastic in Enfield Wash is done by someone who does this every day.

Outside work in London starts with access: side passages, upper floors and where to park. In Enfield Wash, joints up high may need ladders or other access, which is worth talking through when you book.

Every job comes with our 12-month guarantee, wherever you are in Greater London.

Why act early in Enfield Wash

Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble.

The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.

Why book with us

  • Homes, businesses and hotels
  • Tidy, careful work
  • 20+ years of sealant experience
  • Full insurance on every job

Enfield Wash questions

Is parking an issue for external mastic in Enfield Wash?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

Can you do external mastic in Enfield Wash?

Yes. Our work covers London and the South East, and Enfield Wash is part of that. You can phone 07833 053749 or email us and let us know what needs doing, and we will send you a clear quote.

When is the sealant fully cured?

That depends on the sealant used, so follow the cure time we give you when we finish.

Is there a guarantee?

Yes. Each job is guaranteed for twelve months.

Is it OK to seal over old sealant?

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.

Can you seal joints between two different materials?

Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.

Can tenants book the work?

Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.

Is it messy?

Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.

External mastic in Enfield Wash: local notes

London terraces and converted houses often share gutters, downpipes and walls, so it’s worth agreeing who is responsible before work starts. With historic houses such as Forty Hall (about 1.3 miles west) nearby, there’s older building stock in the area around Enfield Wash as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.

Managing a site like Eastfield Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. Enfield Wash is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Common problems we fix in Enfield Wash

Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.

People normally contact us after spotting something like this:

  • Failed seals between different materials
  • Damp patches traced to an open external joint
  • Weeds or debris growing in open joints
  • Failed sealant between panels on a façade

For landlords with property near Turkey Street station, split movement joints are easy to miss on a rental until damp shows inside.

Questions to ask before booking

  • How hidden problems are handled
  • Who does the work, and how experienced they are
  • The length of the guarantee
  • Which colour the sealant will be

10 questions to ask before you book

For landlords and businesses

For anyone letting property in or around Enfield Wash, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

DIY versus a professional finish

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

How the visit works

Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. It 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. Mention any building rules, key holders or managing agents when you book.

  1. We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
  2. We cut out the failed sealant and rake out any dirt or growth.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

How to prepare

  • Let us know about stairs, lifts or work at height
  • Mention any parking rules near the property
  • For indoor joints, keep the area dry beforehand if you can

What the job involves on each surface

Concrete and blockwork

Big joints in concrete need careful depth control. We size the backing rod to the gap so the sealant is not too deep.

Cladding and façade panels

If the façade has a specified sealant, that’s what we use, or one the system allows. Tell us what the building has when you get in touch.

When it is not the sealant

To be straight with you, some problems need a different trade:

  • Rising or penetrating damp from elsewhere in the wall
  • Subsidence or other structural problems
  • Cutting new joints into brickwork, which is building work rather than sealant work

Not sure which it is? You can call 07833 053749 or drop us an email and we will tell you honestly.
