Window mastic near Eversholt

Window mastic for homes and businesses in Eversholt

The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on patio & French doors, timber windows & doors and window sills, and the jobs we see most are mastic that has split away from the wall and draughts coming in around windows and doors.

In a village or hamlet like Eversholt, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Landlord and commercial work in Eversholt

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

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

What window mastic looks like in Eversholt

With historic houses such as Flitwick Manor (about 1.9 miles east) nearby, there’s older building stock in the area around Eversholt as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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 Church of St Lawrence, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Flitwick station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

How to look after the new joints

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

  • Wash the frames with mild soapy water
  • Avoid blasting the frames with a pressure washer
  • Check the mastic once a year
  • Keep solvents and bleach off the sealant

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

Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

What happens on the day

Before we leave, we go over the finished joints with you. 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. Somewhere as small as Eversholt, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We check each frame and agree which ones need doing.
  2. We remove the old mastic and clean the frame and the wall.
  3. Where gaps are deep, backing rod goes in first.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. Every joint is checked before we leave.

Getting ready for the visit

  • Tell us if parking is tricky
  • Let us know about stairs, lifts or work at height
  • For indoor joints, keep the area dry beforehand if you can

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Surface by surface

Patio & French doors

Door frames take knocks and movement every time the doors are used. The sealant must cope with it.

Window sills

Where a sill meets brick or render, the ends often crack first. A tight seal at each end keeps rain out of the wall.

Common questions in Eversholt

Do you work for landlords with property near Flitwick station?

Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear quote.

Will you come out to Eversholt?

Yes, Eversholt is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Can new window sealant be painted?

Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.

Can you do the inside joint as well?

Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.

Will the old sealant be removed?

Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.

Will resealing my frames help with draughts?

Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we’ll say so.

Are you ARBOMaster approved?

Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.

Do you have insurance?

Yes. We’re fully insured.

Why deal with it now?

The work is quick compared with the damage it prevents: the visit takes most of a day for a typical house, less for a few frames. Leave it until water is coming in and you may need plastering and decorating as well. In a small place like Eversholt, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What affects the quote in Eversholt

There’s no set price list, because jobs vary so much. The quote depends on:

  • Which sealant suits the joint
  • The number and length of the joints
  • Whether the work is at height
  • Any working-time requirements on site

Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

Helping us quote

To make quoting easier, please include:

  • Where the property is
  • Whether it has been sealed before
  • If it’s domestic, commercial or a hotel
  • Access, such as stairs, a lift or height
