Honest limits

New sealant cannot fix everything, and we’d rather say so up front. It will not solve:

  • Soft or decayed wood in the frame
  • Penetrating damp from a failed cavity tray or render
  • Faulty window hardware

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

How we handle window mastic in Lacey Green

A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. We work on window sills, composite doors and aluminium frames, and people most often call us about draughty joints inside around the window and mastic that’s falling out in pieces.

Outdoor sealant needs dry, clean surfaces, so work on frames around Lacey Green is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Aftercare tips

Looking after new joints is easy:

  • Check the mastic once a year
  • Use gentle cleaners on frames and sealant
  • Keep drainage slots and sill grooves clear
  • Keep timber frames painted

Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.

A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.

How it works

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a morning for a couple of windows and a door and we leave things clean and tidy. For a village or hamlet like Lacey Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We check each frame and agree which ones need doing.
  2. We remove the old mastic and clean the frame and the wall.
  3. We fit backing rod in deep gaps so the sealant is the right depth.
  4. We apply a weatherproof sealant to match the frame and tool it neatly.
  5. Every joint is checked before we leave.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Let us know about stairs, lifts or work at height
  • Clear the area around the work

For landlords and businesses

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.

How we quote for window mastic

We do not publish a price list, because no two jobs are the same. What we look at:

  • The product the joint needs
  • Mould in or behind the old joints
  • The old material and how stubborn it is
  • Working hours on commercial sites

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What we need to know

You don’t need to know the technical terms. Just tell us:

  • Pictures of the joints, sent by email
  • Whether it’s a home or a business
  • What the problem is, such as mould, gaps, leaks or cracking
  • How many joints, rooms or windows are involved

Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. Whenever you are ready, call 0345 464 0079 or send us an email.

Lacey Green homes and the weather

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as West Wycombe Park House (about 3.8 miles south) nearby, there’s older building stock in the area around Lacey Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

For an older house near a landmark such as Church of St John the Evangelist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Saunderton station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Managing a site like St John's Church of England Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.

How the job changes by surface

Window sills

Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.

Aluminium frames

Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.

Why act early in Lacey Green

Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Where a wall is exposed, as many are in small places like Lacey Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before any work starts.

Your questions about window mastic in Lacey Green

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

Yes, we work for letting agents and landlords. 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.

Is Lacey Green within the area you cover?

Yes, Lacey Green is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Will resealing my frames help with draughts?

Yes, if the air is getting in around the frame. If it’s coming through the window seals, we will tell you.

Do you take out the old sealant first?

Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.

When is the sealant fully cured?

Cure times vary by product and the conditions. We tell you how long to leave it before we go.

Will you leave a mess?

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

Are you an approved applicator?

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
