Window mastic for Penton Grafton homes and businesses

Window mastic in Penton Grafton, done properly

Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you have gaps left after new windows were fitted and black, perished sealant on frames, we can help, whatever the surface.

Outdoor sealant needs dry, clean surfaces, so work on frames around Penton Grafton is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

All our work comes with our one-year guarantee.

Should I try it myself first?

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Penton Grafton questions

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

Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.

Is Penton Grafton within the area you cover?

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can you do upstairs windows?

Yes, in most cases. Access is planned before any work starts.

Is there any odour?

Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.

What do you need from me for a quote?

A short description and the location, with pictures by email if possible. We’ll ask anything else we need to know.

Can you get sealant to suit coloured frames?

Generally, yes. Mention the frame colour when you ask for a quote and we’ll use the nearest match.

Does someone need to be in?

It depends on the job. For work indoors, someone needs to let us in.

Is the new sealant paintable?

It depends on the sealant. Some hybrid sealants can be painted; silicone cannot. Mention any painting plans before we start.

Different surfaces, different methods

Timber windows & doors

Soft or rotten wood cannot be sealed successfully. We will point out any rot we find, as a joiner will need to deal with it.

Composite doors

Draughts round the door leaf normally come from worn seals or adjustment, not the mastic. We seal the frame and let you know about anything else.

How it works

On the day, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work starts. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Penton Grafton, the journey is planned in advance: 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. First, we confirm safe access to each frame.
  2. All the failed sealant is cut away.
  3. Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. We tool the joint so water runs off, then clear up.

Preparing for the visit

  • On commercial sites, let us know about site rules
  • For indoor joints, keep the area dry beforehand if you can
  • Clear items away from the joints we are working on

Why it’s worth doing now in Penton Grafton

Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Around Penton Grafton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear quote before work begins.

Penton Grafton homes and the weather

Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Managing a site like Harrow Way Community School? Then larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Holy Trinity Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Andover station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What sealant work can’t fix

We won’t take on work that won’t last, so here’s what sealant cannot put right:

  • A failed sealed unit that has misted up
  • Damp coming through the wall itself rather than the frame joint
