How we handle new build mastic in Greenbank

We work in new homes and on new-build sites across Greenbank. One shower or a whole phase of plots, the method doesn’t change: cut out, clean, prime where needed and reseal neatly. Common call-outs are for gaps opening as the house dries out and settles and smeared, uneven beads picked up at snagging, across bathrooms & en suites, plot handovers and kitchens.

New flats and houses are still being built in and around Scotland’s cities, and in new homes, sealant and floor joints are often among the first snags, in Greenbank as anywhere.

All our work comes with our one-year guarantee, wherever you are in Edinburgh.

What affects the cost of new build mastic

We don’t publish a price list, because no two jobs are the same. The quote depends on:

  • How much old sealant there is and how hard it is to remove
  • Which sealant suits the joint
  • Access and height
  • How much there is to do

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Asking for a quote

When you contact us, these details help:

  • How many joints, rooms or windows are involved
  • Any previous sealing or DIY work
  • What’s wrong with the joints now
  • Pictures of the joints, sent by email

Every job is quoted individually, so the first step is telling us about yours. Just drop us a line at info@mrmastic.co.uk with the details.

Signs you need new build mastic in Greenbank

Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.

Most people get in touch when they notice one of these:

  • Gaps opening as the house dries out and settles
  • Sealant that never bonded to the surface
  • Messy sealant that spoils new finishes
  • Plot mastic for developers ahead of handover

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

What your quote should include

  • Whether they’re fully insured
  • Who does the work, and how experienced they are
  • Which colour the sealant will be
  • What the cure time is

What the job involves on each surface

Windows and doors

On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.

Show homes

In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.

Landlords, agents and businesses in Greenbank

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.

FAQs for Greenbank

Do you work for landlords with property near Slateford station?

Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.

Do you cover Greenbank for new build mastic?

Yes, Greenbank is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.

Where is Mr Mastic based?

We’re based in Crawley, and we work across South East England, London and Scotland.

How do I get a quote for new build mastic in Greenbank?

Size, access and the old material all affect the cost. Ask us for a quote.

Why has my new-build shower seal failed already?

Cracking in the first couple of years is common. Poor preparation at handover adds to it.

Do you remove the old sealant?

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

Is it worth trying it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.

Looking after it afterwards

So the new joints stay in good condition:

  • Look at the sealant regularly in the first couple of years
  • Wipe joints with warm soapy water
  • Resist patching a failed seal with a tube from the DIY shop
  • Photograph failed sealant before it’s redone

Follow the cure time we give you before the area gets wet. Silicone is usually left for about a day to cure enough for use.

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.

How the visit works

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on the number of plots from start to finish. For a tenement in Greenbank, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. The failed sealant is removed completely, with no layer left behind.
  3. Joints are vacuumed and cleaned of building dust.
  4. Primer goes on where the surface and product need it, then the new sealant.
  5. We tool every joint neatly and tell you when each area can be used.

Before we arrive

  • Move anything stored near the joints
  • Mention any parking rules near the property
  • Try not to wet indoor joints just before the visit

DIY sealant or a professional job?

A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
