External mastic near Kintbury

External mastic in Kintbury

Getting the depth right is half the job. 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. We work on copings & trims, façade panels and joints between brick and frames, and people most often call us about brick movement joints where the sealant has split and gaps where render, brick and frames meet.

Older homes in small places like Kintbury may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.

A one-year guarantee comes as standard.

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What affects the cost of external mastic

Every job gets its own quote. These are the things that affect it:

  • The old material and how stubborn it is
  • How easy the joints are to reach
  • How many areas need sealing
  • The number and length of the joints

What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.

What we need to know

To make quoting easier, please include:

  • The rough size of the job
  • Any access issues, like height or stairs
  • Where the property is
  • Photos by email, if that is easy

To get a quote, call 0345 464 0079 or drop us an email with the location and a short description of the problem. You will have a clear quote before work begins.

Your questions about external mastic in Kintbury

Is Kintbury within the area you cover?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you cover Kintbury for external mastic?

Yes, Kintbury is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.

Can new sealant go over the old?

No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or email us and let us know what needs doing and where.

Do you hold any approvals?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Can you reach joints on upper floors?

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

What external mastic looks like in Kintbury

Historic houses like Benham Park (about 3.4 miles east) are a reminder that the area around Kintbury has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Rented homes near Kintbury station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Homes close to Church of St Mary include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Honest limits

Before you book, it’s worth knowing the limits:

  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Render that is blown, hollow or coming away
  • Walls that need new movement joints cut into them

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

Joints and surfaces we work on

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

Common problems we fix in Kintbury

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 any of the following:

  • Old sealant gone brittle and cracked
  • Panel joints letting water in
  • Damp patches traced to an open external joint
  • Gaps where render, brick and frames meet

For site and facilities teams at buildings such as Kintbury St Mary's C.E. Primary School, larger buildings have long runs of movement joint that eventually need resealing.

How to choose a mastic man

Landlord and commercial work in Kintbury

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.

Leave it or put it right?

It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together. Older cottages and farmhouses around Kintbury can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Combining jobs into one visit is generally more efficient than separate visits. You’ll get one clear quote for the whole job.

How the visit works

Before we leave, we go over the finished joints with you. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on the size of the job. In a small place like Kintbury, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at every joint and agree a colour to suit the wall.
  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. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Keep pets and children clear of the area while we work
  • Let us know about earlier repairs to the joints
