Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. We work on render & cladding joints, joints between brick and frames and brickwork movement joints, and people most often call us about movement joints with cracked, split or missing sealant and failed sealant between panels on a façade.

Around Beacon Hill, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water generally gets in, and they need the right sealant at the right depth.

All of our work is guaranteed for twelve months.

When it isn’t the sealant

New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Adding movement joints to masonry that has none
  • Movement that is more than a sealant joint can take
  • Failed render or damaged cladding panels

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

What we seal

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

Why deal with it now?

Resealing a run of joints in one go is usually better than patching one at a time. Joints of the same age tend to fail together and it means sorting access once. Around Beacon Hill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

DIY versus a professional finish

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, and the work is guaranteed for a year.

If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

What affects the quote in Beacon Hill

For a quick quote, just ask. The main things that affect it are:

  • How many rooms, windows or areas are involved
  • Working hours on commercial sites
  • Whether the work is at height
  • Which sealant suits the joint

The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before we start.

Helping us quote

When you call or email, it’s useful to know:

  • If it’s domestic, commercial or a hotel
  • A few pictures by email, if you can
  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved

To get a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.

What happens on the day

Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a small place like Beacon Hill, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We inspect the joints and agree which need resealing and how they’ll be reached.
  2. The old mastic and anything lodged in the joint is removed.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Preparing for the visit

  • Tell us about any water getting in
  • Move anything stored near the joints
  • Mention any tricky access

Advice

Common questions in Beacon Hill

Will you come out to Beacon Hill?

Yes. Beacon Hill is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you cover Beacon Hill for external mastic?

Yes. We work across London and the South East, and Beacon Hill is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.

How long should I leave it?

That depends on the sealant used, so please follow the time we give you.

Do you remove the old sealant?

Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

When will the joints need doing again?

It varies with how exposed the wall is and how much the joint moves. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.

Should I try DIY first?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

Where are you based?

Our base is Crawley. We work across South East England, London and Scotland.

How much does external mastic cost in Beacon Hill?

Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. A few tips:

  • Point out the joints to other trades
  • Make sure movement joints are not pointed over
  • Keep soil, plants and ivy away from the joints
  • Wash walls gently around the sealant

Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.

Once a joint cannot move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.

Do you need external mastic in Beacon Hill?

Sometimes a movement joint was filled with mortar or a rigid filler by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.

Look out for any of the following:

  • Leaking joints around cladding and façade panels
  • Movement joints with cracked, split or missing sealant
  • Joints pointed up with cement by mistake
  • Rain getting behind render or cladding at a joint

Letting a property close to Witham station? Then split movement joints are easy to miss on a rental until damp shows inside.

Outside joints around Beacon Hill

London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For site and facilities teams at buildings such as Great Totham Primary School, larger buildings have long runs of movement joint that eventually need resealing.
