About our window mastic in Puckeridge

Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before we start. To get one, call 0345 464 0079 or drop us an email with the number of frames and any access details. If you are dealing with a bead that doesn’t match the frame and gaps between the frame and the inside reveal, we can help, whatever the surface.

Houses in smaller places like Puckeridge can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Keep drainage slots and sill grooves clear
  • Use gentle cleaners on frames and sealant
  • Keep timber frames painted
  • Paint up to the joint, not over it

Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or send us an email.

A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.

Signs you need window mastic in Puckeridge

On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.

It’s worth asking for a quote if you see:

  • Cracked internal joints between frame and plaster
  • Cracked sealant at the sill ends
  • Cracked or shrunken mastic around the frame
  • Whistling draughts around closed windows

For an older house near a landmark such as Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.

What to look for in a quote

  • How long the guarantee is
  • How the joint is cleaned and prepared
  • Who does the work, and how experienced they are
  • When the joint can take water or movement

10 questions to ask before you book

Windows and doors in Puckeridge

Historic houses like Much Hadham Palace (about 3.3 miles south-east) are a reminder that the area around Puckeridge has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

Schools such as Roger De Clare First CofE School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Puckeridge is about 5 miles north of Ware, in Hertfordshire. From the centre of Puckeridge to the outskirts, window mastic is available for homes and businesses alike. Puckeridge is one of 381 towns and villages in Hertfordshire where we work for window mastic. There’s also a page for Chelmsford, about 23 miles away.

Your questions about window mastic in Puckeridge

What guarantee comes with window mastic in Puckeridge?

All our work, in Puckeridge and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

Is Puckeridge within the area you cover?

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

What do you need from me for a quote?

Tell us what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.

Is there any odour?

Sometimes, a little. It fades as the sealant cures, and ventilation helps.

Should I try DIY first?

Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

Do you work for letting agents?

Yes, often. Several properties can go on one quote.

Can you do the inside joint as well?

Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.

What do you put in the joint?

Each joint gets the product that suits it. Movement, water and weather all affect the choice.

The process

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. For a job in Puckeridge, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. First we look at every frame and agree the list.
  2. We remove the old mastic and clean the frame and the wall.
  3. Where gaps are deep, backing rod goes in first.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. We clear up and check every joint is fully closed.

Preparing for the visit

  • Clear the area around the work
  • Tell us if parking is tricky
  • For indoor joints, keep the area dry beforehand if you can

What we can’t put right

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Condensation trapped between the panes
  • Damp coming through the wall itself rather than the frame joint
  • A door that needs adjusting, rehanging or new seals

Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

Where we work in Puckeridge

  • uPVC windows
  • Composite doors
  • Timber windows & doors
  • Window sills
  • Aluminium frames
  • Patio & French doors

How the job changes by surface

Aluminium frames

Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.

Timber windows & doors

Timber moves with moisture as well as heat, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.

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.

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.
