How we handle external mastic in Housham Tye

Movement joints let brickwork, render and cladding expand and shrink without cracking. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. Common call-outs are for cracked joints where brick meets render or frames and failed sealant between panels on a façade, across render & cladding joints, brickwork movement joints and copings & trims.

Outside joints can only be sealed when they’re dry, so work in Housham Tye is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.

Every job comes with a 12-month guarantee, wherever you are in Essex.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Fix overflowing gutters above sealed joints
  • Point out the joints to other trades
  • Do not let climbing plants root in the sealant
  • Make sure movement joints aren’t pointed over

Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.

Once a joint cannot move, the wall finds another way, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.

Honest limits

Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:

  • Subsidence or other structural problems
  • Render that is blown, hollow or coming away
  • Cracking across the wall rather than at a joint

If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

Joints and surfaces we work on

  • Copings & trims
  • Joints between brick and frames
  • Concrete & block
  • Brickwork movement joints
  • Render & cladding joints
  • Façade panels

Why act early in Housham Tye

Sealing over the top of old mastic doesn’t hold for long. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. Older cottages and farmhouses around Housham Tye can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

Why book with us

  • A choice of colours where the product allows
  • Fully insured
  • You choose the colour before work begins
  • Every job guaranteed for a year

The process

Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Housham Tye, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. The faces are brushed clean and primed where the product requires it.
  4. We fit closed-cell backing rod to control the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Getting ready for the visit

  • Clear the area around the work
  • Where the joints are inside, avoid wetting them before we arrive
  • Keep pets and children clear of the area while we work
