Why does sealant fail so quickly in new builds?

A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.

Do you take out the old sealant first?

Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

Do you work for landlords and businesses?

Yes. We work for homeowners, landlords, letting agents, businesses and hotels.

Can I do it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

What colour sealant will you use?

That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.

About our new build mastic in Chalkwell

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 that stalls, we can do it. Typical jobs include frame joints opening as the plaster dries and second-fix sealing on new plots, on kitchens, skirting & floors and show homes.

In and around Chalkwell, floors range from older timber boards to tiles and newer finishes, from timber that moves with the seasons to tiles laid on concrete. Skirting and threshold joints need a sealant that suits the floor.

There’s a 12-month guarantee on every job, whatever its size.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

The process

The work is kept neat and contained to the area we’re working on. The job normally takes a few hours for most snagging lists, longer for a run of plots, and we tell you how long to leave it before we go. A visit to Chalkwell is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We look at why each joint failed, including any movement.
  2. We remove the failed sealant and clean the joints.
  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. The finished joints are checked and the cure times given.

Getting ready for the visit

  • Mention any tricky access
  • Mention any parking rules near the property
  • For indoor joints, keep the area dry beforehand if you can

Why act early in Chalkwell

For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. In a smaller place like Chalkwell, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

When to call us in Chalkwell

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 first.

The problems people normally mention when they call include:

  • Gaps behind new kitchen upstands
  • Gaps opening as the house dries out and settles
  • Shower seals failing in the first year or two
  • Cracked sealant around new window and door frames

How to choose a mastic man

What affects the cost of new build mastic

We quote each job individually. These are the things that affect it:

  • How much old sealant there is and how hard it is to remove

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

What the job involves on each surface

Bathrooms and en suites

Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.

Skirting and floors

Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
