Sand mastic in Hillgrove

We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on brick reveals, stone surrounds and timber door frames, and common reasons people get in touch are a silicone bead on a sash window that spoils the look and window mastic to renew ahead of painting.

Somewhere as small as Hillgrove, 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.

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

Hillgrove: your questions answered

Can you do sand mastic in Hillgrove?

Yes. Our work covers London and the South East, and Hillgrove is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing.

I let a flat near Smallbrook Junction station. Can you help?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.

Can you work on commercial sites?

Yes. Hotels, offices and other businesses use us.

Will there be a smell?

It depends on the product. Some products have a noticeable smell, others very little.

Do you remove the old sealant?

Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can new sealant go over the old?

No. The old sealant always comes out first, so the new sealant bonds properly.

What’s sand mastic made of?

A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.

What sand mastic looks like in Hillgrove

With historic houses such as Arreton Manor (about 2.4 miles south) nearby, there’s older building stock in the area around Hillgrove 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Letting a property close to Smallbrook Junction station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. Homes close to St. Mark's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Wootton Community Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What affects the quote in Hillgrove

The price is agreed before any work begins. It’s based on:

  • The old material and how stubborn it is
  • Access and height
  • How much there is to do
  • Any working-time requirements on site

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Asking for a quote

When you contact us, these details help:

  • Any access issues, like height or stairs
  • Roughly how big the job is
  • Where the property is
  • Pictures of the joints, sent by email

Asking for a quote is easy: let us know what needs doing and where. A few photos by email make the job easier to understand, and we will take it from there.

Aftercare tips

To keep the joints looking good and working properly:

  • Get any rot dealt with first
  • Check the mastic when you check the paintwork
  • Avoid heavy scraping on the mastic joint
  • Keep modern sealant off the mastic

When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.

It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.

Why it’s worth doing now in Hillgrove

Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. In a small place like Hillgrove, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry 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. Your quote takes all of that into account.

The process

There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours per window, depending on the condition of the joints, including the tidy-up. Somewhere as small as Hillgrove, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at the surrounds with you and agree the joints to renew.
  2. We remove the old, loose mastic.
  3. We pack any deep voids first.
  4. We apply the mastic by hand and shape it.
  5. The surface is finished to suit the stone or brick.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any tricky access
  • Clear items away from the joints we are working on

How to get a quote

DIY versus a professional finish

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, and the work is guaranteed for a year.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
