Why it’s worth doing now in Great Hampden

It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. Where a wall is exposed, as many are in small places like Great Hampden, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

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. The price is agreed before we begin.

  • Anti-fungal sanitary silicone in wet areas

New build mastic in Great Hampden

Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We work on windows & doors, bathrooms & en suites and plot handovers, and the jobs we see most are sealant that never bonded to the surface and skirting joints opening in the first winter.

Somewhere as small as Great Hampden, 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.

We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Common problems we fix in Great Hampden

Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak, and the problem shows up after you move in.

Keep an eye out for any of the following:

  • Messy sealant that spoils new finishes
  • Internal frame sealant that has split
  • Second-fix sealing on new plots
  • Gaps behind new kitchen upstands

Around Great Hampden, as everywhere, new build mastic is only as good as the preparation behind it.

How to choose a mastic man

Different surfaces, different methods

Kitchens

Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.

Show homes

Show homes need sealant that looks right from day one. Every bead is neat and coloured to suit the room.

What sealant work can’t fix

A few problems are outside what sealant work can do:

  • A tray or bath that isn’t properly supported, until it’s fixed
  • Leaking fittings rather than failed sealant
  • Disputes or warranty claims with your builder

Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before you book.

The process

We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. It normally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Great Hampden, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Each joint is checked for movement before work begins.
  2. Old sealant is cut out and the joints cleaned.
  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. We check every joint and leave you with the cure times.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Move anything stored near the joints
  • Let us know about stairs, lifts or work at height

FAQs for Great Hampden

Do you cover Great Hampden for new build mastic?

Yes. We work across London and the South East, and Great Hampden is part of that. You can ring 0345 464 0079 or email us and let us know what needs doing, and we’ll send you a clear quote.

Do you cover smaller places like Great Hampden?

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

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

No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.

Will you leave a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

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 with our 12-month guarantee.

Are you ARBOMaster approved?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Do you work for letting agents?

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

Can I add another job to the visit?

Yes, we can. More than one area can be quoted together.

How we quote for new build mastic

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

  • The product the joint needs
  • Any working-time requirements on site
  • How easy the joints are to reach
  • How much there is to do

Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

What to tell us for a quote

When you call or email, these details help:

  • A few pictures by email, if you can
  • Where the property is
  • Any access issues, like height or stairs
  • If it’s domestic, commercial or a hotel

We quote each job on its own. Just call 0345 464 0079 or email us with the details, and pictures are welcome.

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
