How to look after the new joints

To keep the joints looking good and working properly:

  • Don’t aim a pressure washer at the joints
  • Make sure the drainage slots aren’t blocked
  • Keep paint and stain on wooden frames in good order
  • Don’t use solvent cleaners on the joint

On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.

On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

Landlord and commercial work in Sutton-under-Brailes

Landlords and agents in Sutton-under-Brailes can book us as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.

Surface by surface

Composite doors

Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.

Timber windows & doors

Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.

The process

On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. The work usually takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Sutton-under-Brailes needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We check each frame and agree which ones need doing.
  2. The old mastic is cut out and the surfaces cleaned back.
  3. We fit backing rod in deep gaps so the sealant is the right depth.
  4. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. We clear up and check every joint is fully closed.

Getting ready for the visit

Should I try it myself first?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

What window mastic looks like in Sutton-under-Brailes

The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

When to call us in Sutton-under-Brailes

Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.

The most common problems we see are:

  • Damp patches on the reveal after heavy rain
  • Gaps between the frame and the inside reveal
  • Old mastic that has gone black or come away
  • White mastic on grey or black frames

Around Sutton-under-Brailes, as everywhere, window mastic is only as good as the preparation behind it.

Choosing a sealant specialist

Why it’s worth doing now in Sutton-under-Brailes

Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Where a wall is exposed, as many are in small places like Sutton-under-Brailes, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Every job is a little different, 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’ll explain the quote if you ask.
