How we handle external mastic in Bledlow

We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the joint does not stand out. We work on render & cladding joints, concrete & block and joints between brick and frames, and the jobs we see most are failed sealant between panels on a façade and moss and dirt in joints with no sealant left.

Somewhere as small as Bledlow, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.

Each job carries a 12-month guarantee.

Aftercare tips

To keep the joints looking good and working properly:

  • Show decorators and builders where the movement joints are
  • Leave the joints unpainted unless we’ve said otherwise
  • Keep soil, plants and ivy away from the joints
  • Never let anyone fill a movement joint with mortar

Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.

Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.

External mastic in Bledlow: local notes

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 Princes Risborough station, outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Church of the Holy Trinity include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. If you look after a building such as Princes Risborough School, larger buildings have long runs of movement joint that eventually need resealing.

Questions from Bledlow

Can you help a landlord with a rental near Princes Risborough station?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.

Is Bledlow within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you guarantee your work?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done and you will get one quote.

Do you seal joints where cladding meets other materials?

Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces.

Do you work for hotels and businesses?

Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.

How much does external mastic cost in Bledlow?

It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.

Can a movement joint be filled with mortar?

No. Rigid materials cannot move with the wall. If it has already been filled, we can normally cut it out and reseal it.

What the job involves on each surface

Concrete and blockwork

The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it.

Cladding and façade panels

If the façade has a specified sealant, that’s what we use or an approved alternative. Tell us what the building has when you get in touch.

The process

We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job generally takes anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. Somewhere as small as Bledlow, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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

  • Clear the area around the work
  • Mention any leaks or damp you’ve noticed
  • Mention any parking rules near the property

Advice

When it is not the sealant

To be straight with you, some problems need a different trade:

  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Cracks in the bricks or render themselves, away from the joints
  • Structural movement, which needs a surveyor or engineer

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

Where we work in Bledlow

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

Why it’s worth doing now in Bledlow

Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. In a small place like Bledlow, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Why us?

  • Sanitary silicone with an anti-fungal additive in wet areas
  • Quality sealants from Arbo and Everbuild
  • Every job guaranteed for a year
  • Over 20 years’ experience

What to tell us for a quote

Before you ask for a quote, have a think about:

  • Whether it has been sealed before
  • Where the property is

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
