New build mastic in Thrupp, done properly

A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. If you have shower seals failing in the first year or two and joints pulling apart as timber shrinks, we can help, whatever the surface.

Around Thrupp, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.

Our work is backed for twelve months, in Thrupp and everywhere else we cover.

Surface by surface

Show homes

We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.

Kitchens

Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.

What we can’t put right

It helps to know what we cannot do:

  • A tray or bath that isn’t properly supported, until it’s fixed
  • Cracked trays, tiles or worktops
  • Deciding who is responsible under a builder’s warranty

If in doubt, phone 0345 464 0079 or email us and we will say what we think.

What we do, step by step

Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on the number of plots. Somewhere like Thrupp needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First, the list of joints is agreed from your snagging sheet or plot schedule.
  2. Every bit of the old builder’s sealant is cut out.
  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. Each bead is tooled and the cure times explained.

Preparing for the visit

  • Tell us if parking is tricky
  • Mention any tricky access

Why deal with it now?

A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Around Thrupp, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

What new build mastic looks like in Thrupp

Looking after it afterwards

So the new joints stay in good condition:

  • Ventilate bathrooms well, especially in the first year
  • Wipe joints with warm soapy water
  • Get a leaking seal dealt with straight away
  • Put sealant faults on your snagging list early

Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents.

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.

What affects the quote in Thrupp

Jobs vary more than people expect. The main factors:

  • Whether there’s mould to deal with
  • How much there is to do
  • Working hours on commercial sites
  • Which sealant suits the joint

A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Asking for a quote

Photos help, but a description is a good start. Please mention:

  • How we’d reach the joints
  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • If someone has resealed it before

It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, phone 0345 464 0079 or email us.
