New build mastic in Hill Grove

New build mastic in Hill Grove, done properly

We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. If you’re dealing with joints pulling apart as timber shrinks and messy sealant that spoils new finishes, we can put it right.

Somewhere as small as Hill Grove, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

Every job is covered by our one-year guarantee, wherever you are in Hampshire.

Questions from Hill Grove

Is Hill Grove within the area you cover?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Can you help a landlord with a rental near Botley station?

Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.

Is there any odour?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

When is the best time to reseal in a new build?

For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.

Should I go to my builder first?

While the snagging or warranty period runs, the builder should be your first contact. If it isn’t sorted, or keeps failing, get in touch with us.

Do you use white or clear sealant?

We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.

When it isn’t the sealant

New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Your warranty claim itself, which is between you and the builder
  • Structural cracks in walls or ceilings
  • Leaking fittings rather than failed sealant

If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before booking.

Surfaces we seal

  • Plot handovers
  • Skirting & floors
  • Kitchens
  • Bathrooms & en suites
  • Show homes
  • Windows & doors

How we quote for new build mastic

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

  • How easy the joints are to reach
  • The size of the job
  • Working hours on commercial sites
  • The type of sealant required

The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

What we need to know

What to tell us when you ask for a quote:

  • Any access issues, like height or stairs
  • A few photos by email, if you can
  • What the problem is, such as mould, gaps, leaks or cracking
  • Whether it’s a home or a business

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

For landlords and businesses

If you manage several properties in or around Hill Grove, jobs at different addresses can go on one quote. Send us the addresses and the work at each, and pictures by email help.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

Common problems we fix in Hill Grove

When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly.

The most common problems we see are:

  • Frame joints opening as the plaster dries
  • Worktop and upstand sealant coming away
  • Gaps opening as the house dries out and settles
  • Untidy sealant flagged on a snagging list

Around Hill Grove, as everywhere, new build mastic is only as good as the preparation behind it.

What to look for in a quote

  • Whether VAT is included
  • How long to leave it before use
  • Whether you can choose the colour
  • What happens if they find a problem under the old sealant

The process

We keep the work tidy and contained to the joints we’re treating. Expect the work to take anything from a few hours to several days, depending on the number of plots. Somewhere like Hill Grove needs a little journey planning: let us know about lanes, gates and parking. 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. The failed sealant is removed completely down to clean surfaces.
  3. We clean out the dust and grit left from the build.
  4. We prime where needed and apply a sealant suited to each joint.
  5. We tool every joint neatly and tell you when each area can be used.

Preparing for the visit

  • Mention any tricky access
  • Plan for the work area to be out of bounds to pets and children
  • Mention any sign-in or site rules at work premises

DIY versus a professional finish

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Keep pictures and emails about snagging items
  • Get a leaking seal dealt with straight away
  • Report sealant problems to your builder during the snagging period
  • Open a window or run the fan after bathing

Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it.

Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.
