New build mastic in Port Dundas

Leave it or put it right?

A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In a tenement flat in Port Dundas, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk and we’ll talk you through it.

How we handle new build mastic in Port Dundas

Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on bathrooms & en suites, kitchens and skirting & floors, and people most often call us about messy sealant that spoils new finishes and gaps behind new kitchen upstands.

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.

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

New homes and floors in Port Dundas

Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. The west of Scotland is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.

FAQs for Port Dundas

Is new build mastic in Port Dundas guaranteed?

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

Do you work for landlords with property near Glasgow Queen Street station?

Yes, we work for landlords and agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.

Are you insured?

Yes. We are fully insured, with over 20 years’ experience in sealant work.

Will you leave a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

How long will you be here?

That depends on the amount of work, but most jobs take a few hours for most snagging lists, longer for a run of plots. We will give you a better idea when we quote.

What information do you need?

Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.

Can you reseal over the builder’s sealant?

No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.

Different surfaces, different methods

Skirting and floors

Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.

Show homes

Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish. Tell us when the home is open so we can plan around it.

Landlord and commercial work in Port Dundas

In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.

We regularly work with letting and managing agents. Tell us the address, the job and how access works.

Do you need new build mastic in Port Dundas?

Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, so the bead never bonds properly.

Keep an eye out for these signs:

  • Gaps behind new kitchen upstands
  • Shower seals failing in the first year or two
  • Internal frame sealant that has split
  • Cracked caulk along new skirting

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

Before you book anyone

  • How much experience the applicator has
  • Is the old sealant removed completely?
  • Whether the sealant suits the joint
  • Is VAT in the price?

10 questions to ask before booking

How we quote for new build mastic

For a quick quote, just ask. What matters most is:

  • When we can work, for business premises
  • The number and length of the joints
  • How much old sealant there is and how hard it is to remove
  • How many areas need sealing

Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

What to tell us for a quote

There’s no need for technical detail. It helps if you can tell us:

  • Whether it’s a home or a business
  • Whether it has been sealed before
  • How we’d reach the joints
  • The rough size of the job

If you’re in Port Dundas and need new build mastic, drop us a line at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and you will get a clear quote before we start.

Aftercare tips

Aftercare is simple, and it makes a real difference:

  • Don’t wait for the house to settle if water is getting through
  • Wipe joints with warm soapy water
  • Report sealant problems to your builder during the snagging period
  • Keep photos and emails about snagging items

Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.

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

How it works

The work is kept neat and contained to the area we are working on, so you can carry on as normal. The job generally takes a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Port Dundas, it helps to know the floor, the door entry arrangements and the nearest parking.

  1. We start by going through the snagging items or plot schedule with you.
  2. The failed sealant is removed completely down to clean surfaces.
  3. Joints are vacuumed and cleaned of building dust.
  4. We prime where needed and apply a sealant suited to each joint.
  5. Each bead is tooled and the cure times explained.

How to prepare

  • Clear the area around the work
  • Try not to wet indoor joints just before the visit
  • Mention if the joints have been sealed before
