Window mastic for Broad Green homes and businesses

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Wipe condensation off the frames
  • Keep paint and stain on wooden frames in good order
  • Keep drainage slots and sill grooves clear
  • Look round the frames every year or so

Try not to touch the new joint while it cures, for as long as we advise. Don’t point a pressure washer at the joints.

Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.

Window mastic in Broad Green, done properly

Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before work begins. Just ring 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached. We work on uPVC windows, aluminium frames and composite doors, and common reasons people get in touch are leaking joints at the ends of sills and draughty joints inside around the window.

Around Broad Green, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

All our work is covered by our one-year guarantee, wherever you are in Essex.

Why it’s worth doing now in Broad Green

Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In a small place like Broad Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and agree the price before starting.

Why Broad Green clients choose us

  • We agree the colour with you first
  • We never seal over old sealant
  • Tidy, careful work
  • Anti-fungal sanitary silicone in wet areas

Broad Green questions

I let a flat near Marks Tey station. Can you help?

Yes, we work for landlords and agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.

Is Broad Green in your area for window mastic?

Yes, Broad Green is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.

Do you seal inside as well as outside?

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.

Can I paint over the new sealant?

Do you work on first-floor windows?

Yes, in most cases. We plan safe access before the job.

Can you work on commercial sites?

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

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Windows and doors in Broad Green

Historic houses like Layer Marney Tower (about 4.6 miles south-east) are a reminder that the area around Broad 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Schools such as Honywood Community Science School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Marks Tey station, renewing tired window mastic between tenants heads off draught and damp complaints.

Do you need window mastic in Broad Green?

Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. That is what backing rod is for.

Most people get in touch when they notice one of these:

  • Gaps where the sill meets the wall
  • Black, perished sealant on frames
  • Cold air getting in at the frame edge
  • Damp patches on the reveal after heavy rain

Homes close to Church of St James include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Our hiring checklist

What we do, step by step

At the end, we look at the finished work together. The work normally takes a few hours for a few frames, or a day or more for a whole house, depending on the size of the job. In a small place like Broad Green, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we confirm safe access to each frame.
  2. All the failed sealant is cut away, along with any loose debris.
  3. The surfaces are cleaned and left dry, and primed where the sealant calls for it.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. We tool the joint so water runs off, then clear up.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • Plan for the work area to be out of bounds to pets and children
  • Mention any parking rules near the property

Honest limits

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

  • Penetrating damp from a failed cavity tray or render
  • A failed sealed unit that has misted up
  • Draughts through the window seals rather than the frame
