Trusted new build mastic in Marsh Green

New build mastic in Marsh Green

Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We are often asked to deal with untidy sealant flagged on a snagging list and internal frame sealant that has split, across kitchens, bathrooms & en suites and windows & doors.

In a village or hamlet like Marsh Green, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.

We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

Marsh Green: your questions answered

What guarantee comes with new build mastic in Marsh Green?

Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.

Is Marsh Green in your area for new build mastic?

Yes. Our work covers London and the South East, and Marsh Green is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.

I rent my home. Can I book you?

Of course. Check with your landlord; we can send the quote to them too.

How long before the joint can be used?

Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.

Which products do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will tell you what we’re using.

Will the old sealant be removed?

Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Do I have to be there?

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

What should I tell you?

The location, the problem and the rough size of the job. If you can, email a few photos.

Joints and finishes in Marsh Green homes

Marsh Green is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.

In and around Marsh Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For jobs in and around Marsh Green, choosing the right material for each joint is as important as a tidy finish.

The process

There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours in a single home. In a small place like Marsh Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Each joint is checked for movement before work begins.
  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. The finished joints are checked and the cure times given.

How to prepare

  • For indoor joints, keep the area dry beforehand if you can
  • Mention any leaks or damp you’ve noticed
  • Tell us if parking is tricky

Advice

Surface by surface

Show homes

Tired or marked sealant in a show home can be renewed. We cut it out and reseal neatly.

Kitchens

New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

  • Avoid scourers and strong chemicals on sealant
  • Check bath and shower seals every few months as the house settles
  • Keep pictures and emails about snagging items
  • Ventilate bathrooms well, especially in the first year

Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.

The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.

Landlord and commercial work in Marsh Green

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.

If you manage several properties in or around Marsh Green, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.

DIY versus a professional finish

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What sealant work can’t fix

It helps to know what we can’t do too:

  • Structural cracks in walls or ceilings
  • Broken tiles or a split tray
  • Leaks from pipes, valves or wastes, which need a plumber

If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before you book.

How we quote for new build mastic

Jobs vary more than people expect. The main factors:

  • Any working-time requirements on site
  • Whether old sealant or filler has to be cut out
  • Whether the work is at height
  • The product the joint needs

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Helping us quote

There’s no need for technical detail. Just tell us:

  • Whether it has been sealed before
  • The problem you’ve noticed
  • Access, such as stairs, a lift or height
  • The type of property
