Hockley External Mastic

We cover Hockley for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly.

  • Rigid filler in a joint that should flex
  • Leaking joints around cladding and façade panels
  • Sealant pulling away from one side of the joint

Trusted external mastic in Hockley

What we do, step by step

Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. Parking around Hockley is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. We start by walking round the building and agreeing the joints and the access.
  2. We cut out the old mastic and rake out anything in the joint.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. We fit closed-cell backing rod to control the depth.
  5. We apply the sealant, tool it and check the whole run.

How to prepare

  • Let us know about parking restrictions
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about earlier repairs to the joints

External mastic in Hockley, done properly

On houses, flats and commercial buildings across Hockley, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. Common call-outs are for rain getting behind render or cladding at a joint and weathered mastic that no longer stretches, on brickwork movement joints, copings & trims and façade panels.

Homes around Hockley range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.

Your job is guaranteed for a year, as with all our work.

Surface by surface

Concrete and blockwork

Concrete faces can be dusty and porous, so preparation is key. We prime where the sealant needs it before the bead.

Render joints

The face of render can be soft, so a sealant that stretches easily protects the edges. We prime where the product needs it.

Walls and rooflines in Hockley

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For landlords with property near Hockley station, split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Emmanuel Church Hall, older walls, gutters and the joints where extensions meet them need a flexible sealant.

FAQs for Hockley

Can you help a landlord with a rental near Hockley station?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.

Can you do external mastic in Hockley?

Do you have insurance?

Yes. Full insurance covers our work.

Are you an approved applicator?

Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Is the work guaranteed?

Yes. All our work carries our one-year guarantee.

What is a movement joint?

A vertical gap in a long brick wall is normally a movement joint. It gives the wall room to move, and it should be sealed with a flexible sealant.

Can you seal over the old sealant?

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.

DIY sealant or a professional job?

If you do try it yourself, take your time over the 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.

Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Signs you need external mastic in Hockley

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.

If you can see any of these, it’s time to have the joints looked at:

  • Weeds or debris growing in open joints
  • Failed sealant between panels on a façade
  • Joints with sealant missing in places
  • Rigid filler in a joint that should flex

Schools such as Greensward Academy are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

How to choose a mastic man

Why act early in Hockley

An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. Homes in smaller places like Hockley can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Why Hockley customers choose us

  • Experience in homes, commercial sites and hotels
  • Full insurance on every job
  • Sanitary silicone with an anti-fungal additive in wet areas
  • One-year guarantee on every job

When something else is needed

Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:

  • Rising or penetrating damp from elsewhere in the wall
  • Structural movement, which needs a surveyor or engineer
  • Cutting new joints into brickwork, which is building work rather than sealant work

If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.
