New build mastic for Woodrow homes and businesses

Looking after it afterwards

Simple care keeps the joints in good condition. We recommend:

  • Wait for the cure time before using a resealed shower
  • Record problems with dated pictures
  • Do not wait for the house to settle if water is getting through
  • Resist patching a failed seal with a tube from the DIY shop

Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.

If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.

About our new build mastic in Woodrow

For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. If you have kitchen sealant that has pulled off the wall and gaps opening as the house dries out and settles, we can put it right, whatever the surface.

For a small place like Woodrow, the journey and access are planned in advance, and the work itself is the same as on any site.

All our work is covered by our one-year guarantee.

What affects the cost of new build mastic

You will get a clear quote before we start. It’s based on:

  • When we can work, for business premises
  • Whether old sealant or filler has to be cut out
  • Any mould that needs treating
  • The type of sealant required

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Asking for a quote

You don’t need to know the technical terms. It helps if you can tell us:

  • The address or postcode of the job
  • The type of property
  • How we’d reach the joints
  • If someone has resealed it before

DIY versus a professional finish

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What new build mastic looks like in Woodrow

Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Do you work for developers?

Do you do commercial work?

Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.

Should I try DIY first?

Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.

Is it worth resealing while the house is still settling?

It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.

Is it messy?

No. The area is protected while we work and cleaned up afterwards.

Can you do several jobs on one visit?

Yes. More than one area can go on one quote.

Signs you need new build mastic in Woodrow

A new house holds a lot of water from the build, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart, and sealant that can’t keep up splits.

Look out for any of the following:

  • Gaps between new skirting and floors
  • Gaps opening as the house dries out and settles
  • Messy sealant that spoils new finishes
  • Internal frame sealant that has split

If you’ve bought a new home near Amersham station, the sealant around baths, showers and frames is worth checking in the first year or two.

What your quote should include

  • The length of the guarantee
  • Which colour the sealant will be
  • Whether they’re fully insured
  • What happens if the job turns out different

How to choose a mastic man

What we can’t put right

Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

Surfaces we seal

  • Plot handovers
  • Windows & doors
  • Kitchens

Why it’s worth doing now in Woodrow

A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can ring 0345 464 0079 or drop us an email with a few pictures and we’ll give you a straight answer. Older cottages and farmhouses around Woodrow can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

How it works

The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the number of plots. In a small place like Woodrow, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  3. We make sure the joints are dry and prime them if needed.
  4. Baths are filled with water, then the new sealant is applied.
  5. We check every joint and leave you with the cure times.

Preparing for the visit

  • Let us know about parking restrictions
  • Mention any leaks or damp you’ve noticed
