Hatherden questions

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

Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.

Is Hatherden in your area for window mastic?

Yes. We work across London and the South East, and Hatherden is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we’re using and why.

Will there be a smell?

Possibly a little. It fades as the sealant cures, and ventilation helps.

Can resealing stop a draught around my window?

In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.

How many windows can you do in a day?

Allow a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.

Is the new sealant paintable?

Silicone generally will not take paint. Let us know beforehand, and we’ll use a paintable product where it suits.

Do you work on first-floor windows?

Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.

Window mastic in Hatherden

The mastic around a window or door seals the gap between the frame and the wall. 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. Common call-outs are for gaps between the frame and the inside reveal and untidy mastic left by window fitters, across aluminium frames, composite doors and window sills.

Somewhere as small as Hatherden, 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.

Each job carries a 12-month guarantee, whatever its size.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Keep solvents and bleach off the sealant
  • Don’t paint over the silicone
  • Clean frames with a soft cloth and soapy water
  • Look round the frames every year or so

Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.

On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

DIY versus a professional finish

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.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.

How it works

At the end, we look at the finished work together and tell you how long to leave it. The work normally takes most of a day for a typical house, less for a few frames, depending on the amount of work. In a small place like Hatherden, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First, we go round the frames with you and agree the list.
  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

  • Let us know about earlier repairs to the joints
  • Tell us about any water getting in
  • Where the joints are inside, avoid wetting them before we arrive

What sealant work cannot fix

We will not take on work that will not last, so here’s what sealant cannot put right:

  • Soft or decayed wood in the frame
  • A door that needs adjusting, rehanging or new seals
  • Broken hinges, locks or handles

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

Do you need window mastic in Hatherden?

A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.

The problems people generally mention when they call include:

  • Cold air getting in at the frame edge
  • Sealant in the wrong colour for the frame
  • Leaking joints at the ends of sills
  • Rain getting in at the frame or under the sill

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

10 questions to ask before you book

Landlord and commercial work in Hatherden

Landlords and agents in Hatherden can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.

What the job involves on each surface

uPVC windows

Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.

Patio & French doors

Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.

Windows and doors in Hatherden

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.

Letting a property close to Andover station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Hatherden Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
