How we handle window mastic in Asheldham

Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on aluminium frames, patio & French doors and timber windows & doors, and common reasons people get in touch are hard, cracked sealant around windows and leaking joints at the ends of sills.

Around Asheldham, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

A 12-month guarantee comes as standard.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Keep solvents and bleach off the sealant
  • Paint up to the joint, not over it
  • Keep drainage slots and sill grooves clear
  • Look round the frames every year or so

Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.

Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.

Why it’s worth doing now in Asheldham

Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we’ll tell you. Where a wall is exposed, as many are in small places like Asheldham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.

How the job changes by surface

Timber windows & doors

Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.

Aluminium frames

Coated aluminium needs a compatible sealant, and acetoxy silicones aren’t used, as they can attack some metals. We use a neutral-cure product.

FAQs for Asheldham

Is Asheldham within the area you cover?

Yes, Asheldham is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Can you help a landlord with a rental near Southminster station?

Yes. We work for letting agents and landlords as well as homeowners. You can ring 0345 464 0079 or send us an email with the details for a clear quote.

Can I paint over the new sealant?

Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.

Do you do commercial work?

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

How long does it take to reseal the windows on a house?

That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.

Can you match the sealant to my frames?

Yes. White, brown, anthracite grey, black and clear sealants are all available, so the joint suits the frame.

Will there be a smell?

There can be a smell while the sealant cures, but it fades. Opening a window helps.

Does someone need to be in?

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

What we’re called out for in Asheldham

A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.

The problems people generally mention when they call are:

  • Mastic that has split away from the wall
  • White mastic on grey or black frames
  • Untidy mastic left by window fitters
  • Cracked internal joints between frame and plaster

If you let a flat or house near Southminster station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What your quote should include

  • Who turns up on the day
  • Whether the sealant suits the joint
  • Whether they’re fully insured
  • Whether all the old sealant comes out first

10 questions to ask before you book

How the visit works

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a few frames, or a day or more for a whole house from start to finish. Somewhere as small as Asheldham, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start by checking each window and door with you.
  2. We remove the old mastic and clean the frame and the wall.
  3. We fit backing rod in deep gaps so the sealant is the right depth.
  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.

Getting ready for the visit

  • Let us know about stairs, lifts or work at height
  • Tell us about any water getting in
  • For business premises, tell us about site rules or sign-in

Advice

When something else is needed

Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:

  • Rotten timber, which needs a joiner first
  • A door that needs adjusting, rehanging or new seals
  • A sash or casement that will not close properly

Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.

Surfaces we seal

  • Window sills
  • Composite doors
  • Timber windows & doors

Window mastic in Asheldham: local notes

Asheldham is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

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

Asheldham is about 8 miles south-east of Maldon, in Essex. From the centre of Asheldham to the outskirts, we cover window mastic for every kind of property.
