Window mastic for Felsted homes and businesses

What happens if it’s left?

Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Around Felsted, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Window mastic in Felsted, done properly

Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you have black, perished sealant on frames and rain getting in at the frame or under the sill, we can put it right, whatever the surface.

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

Big or small, you get the same one-year guarantee in Felsted and across Essex.

Can I do it myself?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

The process

When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Felsted, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We check how each frame can be reached safely.
  2. All the failed sealant is cut away.
  3. Frame and wall are cleaned and must be dry before sealing.
  4. Deep voids are backed, then the sealant is gunned in.
  5. The joint is shaped to shed water and the area tidied.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Let us know about earlier repairs to the joints
  • Let us know about stairs, lifts or work at height

Advice

Work for landlords, hotels and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.

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

How to look after the new joints

How long the joints last depends on use and care. We suggest:

  • Look round the frames every year or so
  • Use gentle cleaners on frames and sealant
  • Keep drainage slots and sill grooves clear
  • Paint up to the joint, not over it

Keep the new mastic undisturbed while it cures, following the cure time we give you. Do not point a pressure washer at the joints.

Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.

Common questions in Felsted

Do you cover Felsted for window mastic?

Yes, Felsted is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.

Will you come out to Felsted?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Will there be a smell?

That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Is it OK to seal over old sealant?

No, because it fails. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.

Do I need to be at home?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Do you work for letting agents?

Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.

Can resealing stop a draught around my window?

If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.

Do you guarantee window mastic?

Yes. Every job comes with our one-year guarantee, and we’re fully insured.

Window mastic in Felsted: local notes

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.

If you look after a building such as Felsted Primary School, its window and door frames need their mastic kept sound, just like a home’s.

When to call us in Felsted

Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, and it lets go sooner than it should.

Common reasons people contact us include:

  • Mastic that is falling out in pieces
  • Damp patches on the reveal after heavy rain
  • White mastic on grey or black frames
  • Gaps where the sill meets the wall

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

Our hiring checklist

How the job changes by surface

Window sills

Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.

Composite doors

Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that’s what we find.
