Window mastic near Mapledurwell

About our window mastic in Mapledurwell

From a single sill to a whole house of windows, you’ll get a clear quote before any work starts. Just phone 0345 464 0079 or email us and tell us how many frames there are and how they’re reached. If you have cracked or shrunken mastic around the frame and damp patches on the reveal after heavy rain, we can help, whatever the surface.

Homes in small places like Mapledurwell often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Mapledurwell: your questions answered

Do you cover smaller places like Mapledurwell?

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

I let a flat near Hook station. Can you help?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.

Do you remove the old sealant?

Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.

Does someone need to be in?

If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.

What sealant do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

Are you insured?

Yes, we’re fully insured for domestic and commercial work.

What do you need from me for a quote?

A short description and the location. If we need more, we will ask.

Where is Mr Mastic based?

Mr Mastic is based in Crawley. Our applicators cover Mapledurwell.

Why deal with it now?

The work is quick compared with the damage it prevents: it takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. Around Mapledurwell, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

What we’re called out for in Mapledurwell

Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.

These are the problems we are asked about most:

  • Untidy mastic left by window fitters
  • Damp patches on the reveal after heavy rain
  • Sealant in the wrong colour for the frame
  • Old mastic that has gone black or come away

For an older house near a landmark such as Church of St. Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What your quote should include

  • Whether VAT is included
  • When the joint can take water or movement
  • Which sealant they’ll use, and why
  • What happens if the job turns out different

Our hiring checklist

Landlord and commercial work in Mapledurwell

Frames and glazing around Mapledurwell

Historic houses like The Vyne (about 4.4 miles north-west) are a reminder that the area around Mapledurwell has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Honest limits

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

  • Penetrating damp from a failed cavity tray or render
  • Draughts through the window seals rather than the frame
  • Faulty window hardware

If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

Surfaces we seal

  • Timber windows & doors
  • Composite doors
  • Window sills
  • uPVC windows
  • Aluminium frames
  • Patio & French doors

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Keep paint and stain on wooden frames in good order
  • Clean frames with a soft cloth and soapy water
  • Air rooms to keep condensation down around windows
  • Keep paint off silicone joints

Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.

Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

What we do, step by step

All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. In a small place like Mapledurwell, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we go round the frames with you and agree the list.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Deep gaps get closed-cell backing rod to set the depth.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. Every joint is tooled smooth and checked before we leave.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Move anything stored near the joints
  • Mention any leaks or damp you’ve noticed
