New build mastic near Farringdon

New build mastic in Farringdon, done properly

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 it isn’t put right, get in touch with us. If you’re dealing with joints pulling apart as timber shrinks and frame joints opening as the plaster dries, we can put it right, on windows & doors, plot handovers and kitchens alike.

Older homes in small places like Farringdon often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.

All of our work is guaranteed for twelve months.

How to look after the new joints

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

  • Record problems with dated pictures
  • Put sealant faults on your snagging list early
  • Ventilate bathrooms well, especially in the first year
  • Keep water off fresh sealant until it has cured

Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.

Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.

Farringdon questions

Is Farringdon in your area for new build mastic?

Yes, Farringdon is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.

I let a flat near Alton station. Can you help?

Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.

Will it make a mess?

We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

Do you work through snagging lists?

Yes. Photos of each sealant item help us quote. If something isn’t sealant, we will say so.

Why has my new-build shower seal failed already?

It’s common, and there are normally two reasons: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.

Can you work on commercial sites?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.

Can you quote for more than one area?

Yes, we can. Several rooms, windows or areas can go on one quote.

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

Start with the builder if you’re in the snagging or warranty period. Once that is done, or if they won’t put it right, we will cut it out and reseal it.

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. In a small place like Farringdon, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.

What you get with us

  • Sealant colour chosen to suit
  • A 12-month guarantee on all work

  • We leave the area clean and tidy

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

When to call us in Farringdon

Sealant applied onto damp surfaces doesn’t bond well. Site programmes don’t always leave time for joints to dry before the sealant goes on.

The most common problems we see are:

  • New-build shower sealant that has already split
  • Sealant work across a run of new homes
  • Cracks appearing as a new home settles
  • Worktop and upstand sealant coming away

In and around Farringdon, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

  • When the joint can take water or movement
  • How hidden problems are handled
  • What product goes in the joint

  • What the problem is, such as mould, gaps, leaks or cracking
  • If someone has resealed it before
  • Pictures of the joints, sent by email

How the visit works

On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work generally takes anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Farringdon, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We go through the snagging list or plot schedule and agree the joints to do.
  2. We cut out every bit of the failed or messy sealant.
  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.

How to prepare

  • Plan for the work area to be out of bounds to pets and children
  • Where the joints are inside, avoid wetting them before we arrive
  • Tell us about access, such as stairs, a lift or high-level joints
