Why it’s worth doing now in Chartway Street

Small cosmetic gaps can wait for the house to settle, but water getting through can’t. If you’re unsure which you have, ring 0345 464 0079 or drop us an email with pictures and we will tell you. Where a wall is exposed, as many are in small places like Chartway Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

10 questions to ask before you book

Your questions about new build mastic in Chartway Street

Do you cover smaller places like Chartway Street?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Is Chartway Street in your area for new build mastic?

Yes. We work across London and the South East, and Chartway Street is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.

Do you use white or clear sealant?

White and clear are the most common, but sealant comes in other colours too. We match the colour to the finish.

Why has my new-build shower seal failed already?

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

Yes. We’re fully insured for domestic and commercial work.

Do you guarantee your work?

Yes. Every job comes with our one-year guarantee.

Can I send you my snagging list?

Yes. We often work straight from a snagging list. We will go through the sealant items and agree what we’ll do.

Do you hold any approvals?

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

What new build mastic looks like in Chartway Street

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, 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.

How the visit works

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere like Chartway Street needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. We start by going through the snagging items or plot schedule with you.
  2. The failed sealant is removed completely, with no layer left behind.
  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. Each bead is tooled and the cure times explained.

How to prepare

  • Keep pets and children clear of the area while we work
  • Clear items away from the joints we are working on
  • Mention any tricky access

Advice

What affects the quote in Chartway Street

Jobs vary more than people expect. What affects the quote:

  • Mould in or behind the old joints
  • Whether the work is at height
  • The number of rooms or windows
  • How much old sealant there is and how hard it is to remove

Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we’ll give you an honest view and a quote.

What we need to know

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • What’s wrong with the joints now
  • Access, such as stairs, a lift or height
  • Whether it’s a home or a business
  • The rough size of the job

Asking for a quote is easy: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we will take it from there.

Work for landlords, hotels and businesses

For anyone letting property in or around Chartway Street, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.

How the job changes by surface

Skirting and floors

As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk in a colour to suit.

Show homes

Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
