Can you match the sealant colour to my new kitchen or bathroom?

It depends on the joint: white or clear for most sanitary joints, colours for worktops, floors and frames. We agree the colour before we start.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Should I go to my builder first?

Start with the builder if you are in the snagging or warranty period. If it is not resolved, we’ll cut it out and reseal it.

New build mastic in Green Street

If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. If you are dealing with second-fix sealing on new plots and sealant that never bonded to the surface, we can help, on bathrooms & en suites, plot handovers and windows & doors alike.

Work in a small place like Green Street just needs the journey and access planning, and once on site, the job is the same as anywhere.

Your job is guaranteed for a year, as with all our work.

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 chosen for how the joint moves and where it is, then guaranteed for a year.

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.

Honest limits

We will not take on work that will not last, so these are the limits:

  • Leaks from pipes, valves or wastes, which need a plumber
  • Settlement cracks that need a surveyor
  • Movement caused by a poorly fitted tray or bath

If you’re not sure, just call 0345 464 0079 or drop us an email and we will give you a straight answer.

Surfaces we seal

  • Skirting & floors
  • Plot handovers
  • Bathrooms & en suites
  • Show homes
  • Windows & doors
  • Kitchens

Keeping the joints in good condition

Looking after new joints is easy, and it makes a real difference:

  • Record problems with dated photos
  • Clean sealant with mild detergent, not abrasives
  • Follow the cure time we give you
  • Look at the sealant regularly in the first couple of years

Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. Report any movement in a bath or tray.

Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.

What happens on the day

There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours in a single home, including the tidy-up. Somewhere like Green Street needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
  2. The old bead comes out in full, with no layer left behind.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. Each area is checked and left with its cure time.

Preparing for the visit

  • Let us know about stairs, lifts or work at height
  • Mention if the joints have been sealed before
  • Tell us about any water getting in

Advice

Quotes for new build mastic in Green Street

The price is agreed before any work begins. It takes into account:

  • The type of sealant required
  • How many rooms, windows or areas are involved
  • The number and length of the joints
  • Whether there’s mould to deal with

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Helping us quote

What to tell us when you ask for a quote:

  • How many joints, rooms or windows are involved
  • A few photos by email, if you can
  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it has been sealed before

Asking for a quote is easy: let us know what needs doing and where and its rough size. A few photos by email make the job easier to understand, and we will come back to you with a quote.

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Landlords and agents in Green Street can book us as well as householders. Resealing between tenancies keeps a property looking cared for.

Do you need new build mastic in Green Street?

If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry.

The most common problems we see are:

  • Sealant applied over dusty or wet surfaces
  • Sealant work across a run of new homes
  • Gaps between new skirting and floors
  • Messy sealant that spoils new finishes

In and around Green Street, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How to choose a mastic man

What new build mastic looks like in Green Street

Green Street is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.

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