Window mastic in Nettlebed: 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. With historic houses such as Greys Court (about 2.7 miles south-east) nearby, there’s older building stock in the area around Nettlebed as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

Schools such as Nettlebed Community School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of St Bartholomew, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Landlord and commercial work in Nettlebed

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

We also work for property managers and facilities teams in Nettlebed and across Oxfordshire. We can quote a run of properties together, and we’re fully insured for the work.

Why act early in Nettlebed

A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In a small place like Nettlebed, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Why us?

  • Old sealant always removed completely
  • Anti-fungal silicone where joints get wet
  • We leave the area clean and tidy
  • Homes, businesses and hotels

Nettlebed: your questions answered

Is Nettlebed within the area you cover?

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

Is window mastic in Nettlebed guaranteed?

Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

How long should I leave it?

Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.

Are you insured?

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

I rent my home. Can I book you?

We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.

Can you reach windows above the ground floor?

Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.

How much does window mastic cost in Nettlebed?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before work begins.

Where do you work from?

Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.

What the job involves on each surface

Aluminium frames

Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.

Composite doors

Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We’ll tell you if that is what we find.

Should I try it myself first?

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

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.

The process

When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work normally takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Nettlebed, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. Each frame is looked over and we agree which ones need resealing.
  2. The old mastic is cut out and scraped back to clean surfaces.
  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.

Preparing for the visit

  • Keep pets and children clear of the area while we work
  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints
