Trusted external mastic in Lordswood

External mastic in Lordswood

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 concrete & block, façade panels and brickwork movement joints, and the jobs we see most are movement joints with cracked, split or missing sealant and damp patches traced to an open external joint.

Outbuildings, garages and conservatories around homes in places like Lordswood add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Landlords, agents and businesses in Lordswood

In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

What we do, step by step

We bring everything the job needs with us. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. Parking around Lordswood is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. We start by walking round the building and agreeing the joints and the access.
  2. Every bit of old sealant and any mortar or debris is cut out.
  3. Joint faces are cleaned back and primed if the sealant needs it.
  4. We fit closed-cell backing rod to control the depth.
  5. The exterior sealant is applied, tooled and checked along its length.

Preparing for the visit

  • Let us know about stairs, lifts or work at height
  • Plan for the work area to be out of bounds to pets and children
  • Let us know if you’ve seen damp or leaks

Advice

Do you need external mastic in Lordswood?

Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.

Keep an eye out for these signs:

  • Joints with sealant missing in places
  • Damp patches traced to an open external joint
  • Plants rooting in failed movement joints
  • Sealant that has lost its bond to the brick or render

In the older streets around St David's Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

10 questions to ask before booking

What affects the quote in Lordswood

We quote each job individually. This is what makes a difference:

  • Whether old sealant or filler has to be cut out
  • Whether the work is at height
  • Any mould that needs treating
  • When we can work, for business premises

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Helping us quote

To make quoting easier, let us know:

  • Photos by email, if that’s easy
  • Any access issues, like height or stairs
  • The address or postcode of the job
  • The problem you’ve noticed

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, phone 0345 464 0079 or drop us an email.

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you’ve already had a go yourself, that is fine. We cut it out and start again.

Honest limits

In fairness, there are a few things sealant will not fix:

  • Loose or hollow render, which needs re-rendering
  • Cracks in the bricks or render themselves, away from the joints
  • Damp that isn’t coming from the joint

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

Lordswood questions

Do you work for landlords with property near Chatham station?

Yes, we work for landlords and agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll send you a clear quote.

Do you cover smaller places like Lordswood?

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

Do you have insurance?

Yes. We are fully insured, and we can confirm the details when we quote.

How do you reach high-level joints?

Each building is different. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.

How long does external mastic last?

It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.

Where is Mr Mastic based?

We are a Crawley-based firm. Our area covers South East England, London and Scotland.

Is it OK to fill a movement joint with cement?

No, not if it’s a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. We will reseal it with a flexible sealant.

Is it messy?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Lordswood buildings and the weather

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Restoration House (about 3.9 miles north-west) are a reminder that the area around Lordswood 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.

For site and facilities teams at buildings such as St Benedict's Catholic Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Chatham station, outside joints that have cracked can let damp into a rental, so check them between lets.

What the job involves on each surface
