External & façade joints in Howe Hill, Oxfordshire

We cover Howe Hill for sealing brickwork movement joints, render, cladding and façade joints. Old material cut out, joints cleaned and sealed neatly.

  • Failed seals between different materials
  • Hard, crazed mastic that has stopped moving
  • Movement joints filled with mortar instead of sealant

External mastic for Howe Hill homes and businesses

Why deal with it now?

Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. Older cottages and farmhouses around Howe Hill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

External mastic in Howe Hill

Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. If you have water getting into walls through failed joints and moss and dirt in joints with no sealant left, we can put it right.

Somewhere as small as Howe Hill, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.

A one-year guarantee comes with the work, just as it does everywhere we cover.

What happens on the day

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. Somewhere as small as Howe Hill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. We take out the old sealant until the faces are sound.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. We prime the faces where required.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Plan for the work area to be out of bounds to pets and children
  • Tell us about access, such as stairs, a lift or high-level joints

Getting a quote

Advice

Aftercare tips

Simple care keeps the joints in good condition. We recommend:

  • Show decorators and builders where the movement joints are
  • Walk round the building once a year and look at the joints
  • Ask before painting over external sealant
  • Avoid pressure-washing directly into sealant joints

Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.

Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.

Honest limits

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

  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Structural movement, which needs a surveyor or engineer
  • Cracked brickwork or render that needs a builder or plasterer

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.

What we seal

  • Concrete & block
  • Render & cladding joints
  • Joints between brick and frames

Landlords, agents and businesses in Howe Hill

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

For anyone letting property in or around Howe Hill, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.

Should I try it myself first?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

Howe Hill buildings and the weather

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. With historic houses such as Stonor Park (about 3.2 miles south-east) nearby, there’s older building stock in the area around Howe Hill as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.

Managing a site like Icknield Community College? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Historic houses such as Stonor Park, about 3.2 miles south-east, show how far back building around Howe Hill goes, and older homes nearby need a sealant that suits their walls.
