  • Deciding who is responsible under a builder’s warranty

How we handle new build mastic in Hartley Wintney

Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. If you have untidy sealant flagged on a snagging list and shower seals failing in the first year or two, we can help, on skirting & floors, bathrooms & en suites and show homes alike.

In smaller places like Hartley Wintney, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

My new home is still under warranty. Should I contact you?

Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it and our work is guaranteed for a year.

Can I add another job to the visit?

Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.

Do you take on second-fix sealing for builders?

Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we’ll quote.

Can you work on commercial sites?

Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.

Is it normal for sealant to crack in a new home?

A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.

Will you just run a new bead over the existing one?

No. We always remove the existing bead, then clean and prime the joint, and a new bead applied.

The process

When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours in a single home. Parking around Hartley Wintney is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. We go through the snagging list or plot schedule and agree the joints to do.
  2. Failed or untidy sealant is cut out completely.
  3. We clean off dust from the build and prime the surfaces where the product needs it.
  4. We apply a sealant that suits each joint and tool it to a neat finish.
  5. Finally, each room is checked and you’re given the cure time.

Preparing for the visit

  • Mention any parking rules near the property
  • Try not to wet indoor joints just before the visit
  • Mention any tricky access

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Quotes for new build mastic in Hartley Wintney

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Any mould that needs treating
  • How much there is to do
  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out

The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.

What to tell us for a quote

Photos help, but a description is a good start. Try to tell us:

  • How we’d reach the joints
  • The type of property
  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

Why deal with it now?

It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. In an older home around Hartley Wintney, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Why us?

  • We agree the colour with you first
  • We’re fully insured
  • Domestic, commercial and hotel work
  • Any old sealant cut out fully, not covered over

See our cost guide and customer reviews.

Keeping the joints in good condition

How long the joints last depends on use and care. We suggest:

  • Watch for new gaps as the house dries out
  • Wait for the cure time before using a resealed shower
  • Clean sealant with mild detergent, not abrasives
  • Do not wait for the house to settle if water is getting through

Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day.

Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

For landlords and businesses

We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
