About our new build mastic in Colinton

Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. If you are still within the builder’s snagging or warranty period, tell them first. If you have second-fix sealing on new plots and new-build shower sealant that has already split, we can put it right, on skirting & floors, kitchens and show homes alike.

New flats and houses are still being built in and around Scotland’s cities, and new-home owners often find sealant snags in the first year or two, in Colinton as anywhere.

All our work comes with a one-year guarantee.

Common questions in Colinton

I let a flat near Kingsknowe station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.

Is there a guarantee on new build mastic in Colinton?

All our work, in Colinton and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Do you work through snagging lists?

Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we will do.

Should I wait before resealing?

Any seal that is leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.

Do you hold any approvals?

Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

What do you need from me for a quote?

Let us know what needs doing and where, with pictures by email if possible. If we need more, we will ask.

Do I need to be at home?

We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.

Can new sealant go on top of the old bead?

No. New silicone will not bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.

New build mastic in Colinton: local notes

Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.

How the job changes by surface

Plot handovers

We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed to keep callbacks down.

Show homes

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

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, 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.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Aftercare tips

A little care helps the new joints last. Our advice:

  • Photograph failed sealant before it’s redone
  • Avoid scourers and strong chemicals on sealant
  • Keep water off fresh sealant until it has cured
  • Report sealant problems to your builder during the snagging period

Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.

Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.

Do you need new build mastic in Colinton?

Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.

If you can see any of these, it’s time to have the joints looked at:

  • Cracked sealant around new window and door frames
  • Smeared, uneven beads picked up at snagging
  • Plot mastic for developers ahead of handover
  • Gaps opening as the house dries out and settles

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

What your quote should include

  • When the joint can take water or movement
  • Whether VAT is included
  • How hidden problems are handled
  • How the surfaces are prepared before sealing

10 questions to ask before booking

How the visit works

All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours in a single home. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Colinton, it helps to know the floor, the door entry arrangements and the nearest parking.

  1. We look at why each joint failed, including any movement.
  2. Old sealant is cut out and the joints cleaned.
  3. Joints are dried and primed where the product calls for it.
  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 earlier repairs to the joints
  • Let us know about parking restrictions
  • Try not to wet indoor joints just before the visit

Advice

Quotes for new build mastic in Colinton

Some jobs are bigger than they look, and some smaller. The main factors:

  • Mould in or behind the old joints
  • The amount of work
  • Whether old sealant or filler has to be cut out
  • How many areas need sealing

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

What to tell us for a quote

When you contact us, these details help:

  • If someone has resealed it before
  • Where the property is
  • Pictures of the joints, sent by email
  • Whether it’s a home or a business
