Window & door mastic in Cole End, Essex

Problem with your window and door frames in Cole End? We cut out the old, prepare the joints and apply the right sealant.

  • Leaking joints at the ends of sills
  • Cracked or shrunken mastic around the frame

Window mastic for Cole End homes and businesses

Window mastic for homes and businesses in Cole End

A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have untidy mastic left by window fitters and damp patches on the reveal after heavy rain, we can put it right, on aluminium frames, patio & French doors and timber windows & doors alike.

Mastic can only go onto a dry, clean joint, so window work in Cole End is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

Big or small, it’s backed by our 12-month guarantee.

Do you need window mastic in Cole End?

Frames are never completely still. 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.

Any of these means the joints need attention:

  • Draughts coming in around windows and doors
  • Cracked or shrunken mastic around the frame
  • Gaps where the sill meets the wall
  • Old mastic that has gone black or come away

For landlords with property near Audley End station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Choosing a sealant specialist

Can I do it myself?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

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 doesn’t work out, we can still put it right.

What sealant work cannot fix

New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:

  • Soft or decayed wood in the frame
  • Draughts through the window seals rather than the frame
  • Damp problems in the wall away from the window

If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before booking.

Joints and surfaces we work on

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

Different surfaces, different methods

Composite doors

Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.

uPVC windows

Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.

What window mastic looks like in Cole End

Historic houses like Audley End House (about 2.9 miles west) are a reminder that the area around Cole End has older buildings as well as new. Where a home is older, 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For an older house near a landmark such as St James' Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Managing a site like Saffron Walden County High School? Then its window and door frames need their mastic kept sound, just like a home’s.

Work for landlords, hotels and businesses

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

What we do, step by step

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for a few frames, or a day or more for a whole house. In a small place like Cole End, access is generally the main thing to plan. 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. The old mastic is cut out and scraped back to clean surfaces.
  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

  • For business premises, tell us about site rules or sign-in
  • Tell us about any previous sealing or DIY attempts
  • Plan for the work area to be out of bounds to pets and children
