What affects the quote in Lower Titmore Green

The quote reflects the job in front of us. We take into account:

  • How many areas need sealing
  • The product the joint needs
  • The number and length of the joints
  • Access and height

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 we need extra access for height. We take all of that into account in your quote.

Window mastic for homes and businesses in Lower Titmore Green

Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on window sills, composite doors and patio & French doors, and people most often call us about damp patches on the reveal after heavy rain and rushed sealant from a window installation.

Somewhere as small as Lower Titmore Green, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

Our work is backed for twelve months, in Lower Titmore Green and everywhere else we cover.

How the job changes by surface

Aluminium frames

Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour suits the frame.

Timber windows & doors

Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.

Questions from Lower Titmore Green

Can you do window mastic in Lower Titmore Green?

Yes. Our work covers London and the South East, and Lower Titmore Green is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.

Will you come out to Lower Titmore Green?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.

Is it worth trying it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.

What do you need from me for a quote?

The location, the problem and the rough size of the job. If you can, email a few pictures.

Will there be a smell?

Sometimes, a little. Any smell clears as the sealant cures.

How long will my window job take?

It depends on access, the old mastic and the size of the frames. We will tell you how long your job needs when we quote.

Are you an approved applicator?

Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.

Can I do it myself?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

Lower Titmore Green homes and the weather

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Knebworth House (about 3.5 miles south) are a reminder that the area around Lower Titmore Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

For site and facilities teams at buildings such as Wymondley Junior Mixed and Infant School, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Stevenage station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Church of St Mary the Virgin, the joint between an old wall and a newer frame is normally the first place rain gets in.

How the visit works

There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. Somewhere as small as Lower Titmore Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each frame is looked over and we agree which ones need resealing.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Where the gap is deep, backing rod goes in first.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. We tool each bead neatly and check every joint is closed.

Getting ready for the visit

  • Move anything stored near the joints
  • Tell us if parking is tricky
  • Tell us about access, such as stairs, a lift or high-level joints

Aftercare tips

To keep the joints looking good and working properly:

  • Keep paint and stain on wooden frames in good order
  • Avoid blasting the frames with a pressure washer
  • Look round the frames every year or so
  • Wipe condensation off the frames

Keep sill grooves and drainage slots clear, 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.
