Window mastic for Ufton Green homes and businesses

Window mastic for homes and businesses in Ufton Green

Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. If you have rain getting in at the frame or under the sill and black, perished sealant on frames, we can put it right, whatever the surface.

Around Ufton Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.

What happens on the day

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a morning for a couple of windows and a door. Somewhere like Ufton Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  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. Deep voids are backed, then the sealant is gunned in.
  5. We tool the joint so water runs off, then clear up.

Preparing for the visit

  • Let us know about parking restrictions
  • Let us know about earlier repairs to the joints
  • Clear the area around the work

What window mastic looks like in Ufton Green

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Schools such as Sulhamstead and Ufton Nervet School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Homes close to Church of St Peter include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Aldermaston station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Ufton Green questions

Is Ufton Green within the area you cover?

Yes, Ufton Green is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

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

Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.

What sealant do you use?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.

Can I paint over the new sealant?

Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.

Is it messy?

Very little: the area around the joints is protected first, and we tidy up before we go.

How long should I leave it?

Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.

How many windows can you do in a day?

A few frames take a few hours. We confirm the timing with your quote.

Looking after it afterwards

No joint lasts for ever, but care makes a real difference. A few tips:

  • Do not use solvent cleaners on the joint
  • Clean frames with a soft cloth and soapy water
  • Keep drainage slots and sill grooves clear
  • Don’t aim a pressure washer at the joints

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

Leaks usually show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

Can I do it myself?

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

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

How we quote for window mastic

We do not publish a price list, because jobs vary so much. What we look at:

  • The size of the job
  • Whether there’s mould to deal with
  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

What to tell us for a quote

To help us quote quickly, let us know:

  • Any access issues, like height or stairs
  • The rough size of the job
  • Where the job is, and your postcode
  • What’s wrong with the joints now

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you are ready, ring 0345 464 0079 or drop us an email.

Why deal with it now?

Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In a small place like Ufton Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.
