About our sand mastic in Corhampton

On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead, and we’ll talk through which suits your home. If you are dealing with failed mastic on an exposed elevation and a silicone bead on a sash window that spoils the look, we can help, on tenement windows, period & listed homes and timber door frames alike.

Somewhere as small as Corhampton, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

Every job is covered by our 12-month guarantee.

How the visit works

A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a single window, longer for several. For a village or hamlet like Corhampton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. We look at the surrounds with you and agree the joints to renew.
  2. We remove the old, loose mastic.
  3. Deep gaps are packed so the mastic sits at the right depth.
  4. We apply the mastic by hand and shape it.
  5. We dress the finish so it sits neatly against the masonry.

Getting ready for the visit

  • Keep children and pets away from the work area
  • Mention any sign-in or site rules at work premises
  • Tell us about access, such as stairs, a lift or high-level joints

Quotes for sand mastic in Corhampton

Your quote is based on your job. We take into account:

  • How many rooms, windows or areas are involved
  • The product the joint needs
  • How much old sealant there is and how hard it is to remove
  • When we can work, for business premises

Leaving a failed joint normally makes the job bigger, not smaller. If you are unsure, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Helping us quote

To make quoting easier, please include:

  • What’s wrong with the joints now
  • Any previous sealing or DIY work
  • Whether it’s a home or a business
  • Access, such as stairs, a lift or height

What happens if it’s left?

New mastic over crumbling mastic will not hold. Raking out and preparing the joint gives it a sound base so the new mastic stays put. Where a wall is exposed, as many are in small places like Corhampton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

Windows and doors in Corhampton

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Hinton Ampner House (about 4.4 miles north) nearby, there’s older building stock in the area around Corhampton as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

In the older streets around Corhampton Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

FAQs for Corhampton

What guarantee comes with sand mastic in Corhampton?

Do you cover smaller places like Corhampton?

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.

Is there any odour?

Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.

Do you hold any approvals?

Can old silicone round a sash window be swapped for sand mastic?

Generally, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.

Should I use sand mastic or silicone?

Sand mastic normally suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we will explain why.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Where is Mr Mastic based?

We are a Crawley-based firm. Our area covers South East England, London and Scotland.

What we are called out for in Corhampton

Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out, which is why we pack deep voids first and get the depth right.

The problems people normally mention when they call are:

  • Mastic dropping out of the joint
  • Failed mastic on an exposed elevation
  • A silicone bead on a sash window that spoils the look
  • Tired mastic found when preparing windows for paint

For site and facilities teams at buildings such as Meonstoke Church of England Infant School, the mastic around its windows and doors needs looking after like any other building’s.

What your quote should include

  • Who turns up on the day
  • Whether the sealant suits the joint
  • The length of the guarantee
  • Whether they seal over old material or remove it
