External mastic in Freezywater

For landlords and businesses

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.

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.

External mastic in Freezywater, done properly

A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. Typical jobs include failed seals between different materials and hard, crazed mastic that has stopped moving, on copings & trims, render & cladding joints and concrete & block. As mastic and silicone sealant specialists, we cover Freezywater for external mastic and other sealant work.

Modern London flats rely on sealed movement joints and cladding joints. Older terraces have their own weak points: gutter joints, roofline trims and the joint where an extension meets the original wall, and both kinds of building are found across London.

Every job is covered by a 12-month guarantee, wherever you are in Greater London.

Do you need external mastic in Freezywater?

A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.

Keep an eye out for these signs:

  • Rigid filler in a joint that should flex
  • Moss and dirt in joints with no sealant left
  • Rain getting behind render or cladding at a joint
  • Weathered mastic that no longer stretches

If you live in an older home near Ss Peter and Paul Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

Choosing a sealant specialist

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Act on the first splits you see
  • Walk round the building once a year and look at the joints
  • Leave the joints unpainted unless we have said otherwise
  • Avoid pressure-washing directly into sealant joints

Don’t paint over the new sealant unless we’ve said the product is paintable. Many exterior sealants are not designed to be painted, and paint can crack as the joint moves.

Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.

What we cannot put right

We will always be straight with you, so here’s what new sealant will not do:

  • Cracked brickwork or render that needs a builder or plasterer
  • Subsidence or other structural problems
  • Failed render or damaged cladding panels

If you are not sure, just phone 07833 053749 or send us an email and we’ll give you a straight answer before booking.

Freezywater buildings and the weather

In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking. Historic houses like Forty Hall (about 1.7 miles west) are a reminder that the area around Freezywater has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

Freezywater is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Letting a property close to Enfield Lock station? Then split movement joints are easy to miss on a rental until damp shows inside.

The process

All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of joints, longer for a whole elevation. In a London area like Freezywater, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  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. We apply the sealant, tool it and check the whole run.

How to prepare

  • Mention any tricky access
  • Tell us about any previous sealing or DIY attempts

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Common questions in Freezywater

Can you help a landlord with a rental near Enfield Lock 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’ll give you a fixed price before work begins.

Can you do external mastic in Freezywater?

Yes, Freezywater is within the area we cover. Our work covers London and the South East. Just call 07833 053749 or drop us an email with a few details of the job, and we’ll send you a clear quote.

Can I add another job to the visit?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Why is there a gap in my brick wall?

It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.

Do you work at height?

That depends on the building and the joints. Where joints can be reached safely, we will do them. Give us some details and we will confirm the access.

Can you seal joints between two different materials?

Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.

Which products do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

How often do external joints need resealing?

That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and reseal when it splits.
