Homes in Edgehill have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on patio & French doors, timber windows & doors and uPVC windows, and people most often call us about draughts coming in around windows and doors and black, perished sealant on frames.

Outdoor sealant needs dry, clean surfaces, so work on frames around Edgehill is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

Can I do it myself?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

When it is not the sealant

In fairness, there are a few things sealant won’t fix:

  • A frame that has rotted at the joint
  • A failed sealed unit that has misted up
  • Faulty window hardware

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

What we seal

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

Looking after it afterwards

Joint life depends on how it’s used and looked after. We suggest:

  • Keep drainage slots and sill grooves clear
  • Keep paint and stain on wooden frames in good order
  • Wipe condensation off the frames
  • Avoid blasting the frames with a pressure washer

Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.

Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

What affects the quote in Edgehill

We do not publish a price list, because no two jobs are the same. The quote depends on:

  • How easy the joints are to reach
  • Whether there’s mould to deal with
  • When we can work, for business premises
  • The type of sealant required

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us and we will talk you through it.

What we need to know

To help us quote quickly, let us know:

  • Photos by email, if that’s easy
  • The problem you’ve noticed
  • The address or postcode of the job
  • If it’s domestic, commercial or a hotel

We quote each job on its own. Just ring 0345 464 0079 or send us an email with the details.

The process

All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Edgehill, 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. First we look at every frame and agree the list.
  2. Next the failed sealant is cut away and the joint cleaned.
  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. Finally we tidy up and check each joint.

Getting ready for the visit

  • Mention any parking rules near the property
  • Clear the area around the work
  • Try not to wet indoor joints just before the visit

Advice

FAQs for Edgehill

Is there a guarantee on window mastic in Edgehill?

All our work, in Edgehill and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Is Edgehill within the area you cover?

Yes. Edgehill 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.

How long does it take to reseal the windows on a house?

The work takes a few hours for a few frames, or a day or more for a whole house. Access and the amount of old mastic make the biggest difference.

Can you do the inside joint as well?

Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.

Will new mastic stop draughts?

In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.

Do I have to be there?

It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Will it make a mess?

Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.

Can I add another job to the visit?

Yes. Tell us about everything you’d like done and we’ll quote it together.

Leave it or put it right?

Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we will tell you. Around Edgehill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will send you a clear quote for the lot.

Why book with us

  • We agree the colour with you first
  • We leave the area clean and tidy

Signs you need window mastic in Edgehill

Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.

The most common problems we see are:

  • Mastic that has split away from the wall
  • A bead that doesn’t match the frame
  • Cracked sealant at the sill ends
  • Whistling draughts around closed windows

Around Edgehill, as everywhere, window mastic is only as good as the preparation behind it.

Before booking anyone

  • What happens if the job turns out different
  • Which sealant they’ll use, and why
  • How long to leave it before use
  • How the surfaces are prepared before sealing

Our hiring checklist

What window mastic looks like in Edgehill

With historic houses such as Upton House (about 1 mile south) nearby, there’s older building stock in the area around Edgehill as well as newer homes. In older buildings, 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

For an older house near a landmark such as Church of St Peter, the joint between an old wall and a newer frame is usually the first place rain gets in.
