Trusted external mastic in Mullenspond

External mastic in Mullenspond

Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. We work on concrete & block, façade panels and brickwork movement joints, and people most often call us about joints with sealant missing in places and moss and dirt in joints with no sealant left.

Somewhere as small as Mullenspond, 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.

All of our work is guaranteed for twelve months.

What we’re called out for in Mullenspond

Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.

The problems people normally mention when they call are:

  • Damp patches traced to an open external joint
  • Old sealant gone brittle and cracked
  • Moss and dirt in joints with no sealant left
  • Joints with sealant missing in places

Schools such as Amport Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

What to look for in a quote

  • Whether all the old sealant comes out first
  • Which colour the sealant will be
  • What guarantee comes with the work
  • What happens if the job turns out different

Our hiring checklist

What the job involves on each surface

Render joints

Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.

Copings and trims

Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible year round.

What affects the quote in Mullenspond

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

  • Which sealant suits the joint
  • How much old sealant there is and how hard it is to remove
  • The size of the job
  • When we can work, for business premises

We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

Helping us quote

There’s no need for technical detail. Just tell us:

  • What’s wrong with the joints now
  • Whether it’s a home or a business
  • Whether it has been sealed before
  • Where the job is, and your postcode

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

What we do, step by step

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Mullenspond, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  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. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Tell us about any previous sealing or DIY attempts
  • Mention any tricky access

Advice

Leave it or put it right?

A failed movement joint lets water into the wall and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. Around Mullenspond, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

What you get with us

  • Quality sealants from Arbo and Everbuild
  • We’re fully insured
  • Experience in homes, commercial sites and hotels
  • A 12-month guarantee on all work

Walls and rooflines in Mullenspond

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.

If you let a flat or house near Grateley station, outside joints that have cracked can let damp into a rental, so check them between lets. For an older house near a landmark such as Church of St Nicholas, an extension built onto an older house moves differently, and the joint between them takes the strain.

Questions from Mullenspond

Do you cover smaller places like Mullenspond?

Yes. Mullenspond 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.

Is Mullenspond in your area for external mastic?

Yes, Mullenspond is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.

Can you seal joints between two different materials?

Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.

Can tenants book the work?

Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.

Will the new joint stand out?

Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint does not draw the eye.

Can you do several jobs on one visit?

Yes. Several rooms, windows or areas can go on one quote.

Can landlords and businesses book you?

Yes, often. Several properties can be quoted together.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

DIY sealant or a professional job?

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.

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

When it is not the sealant

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

  • Render that is blown, hollow or coming away
  • Damp that isn’t coming from the joint
  • Walls that need new movement joints cut into them

If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.
