Window mastic in Hoo St Werburgh

Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for draughty joints inside around the window and cracked sealant at the sill ends, on window sills, uPVC windows and timber windows & doors.

In a smaller place like Hoo St Werburgh, some walls face open ground and catch the full force of the weather. That’s hard on the mastic around frames and sills.

The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What sealant work cannot fix

In fairness, there are a few things sealant will not fix:

  • Draughts through the window seals rather than the frame
  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Damp problems in the wall away from the window

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

Surfaces we seal

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

What affects the quote in Hoo St Werburgh

Jobs vary more than people expect. The main factors:

  • Any working-time requirements on site
  • The number and length of the joints
  • Access and height
  • The product the joint needs

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

What we need to know

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • The rough size of the job
  • Pictures of the joints, sent by email
  • Access, such as stairs, a lift or height
  • What’s wrong with the joints now

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, phone 0345 464 0079 or send us an email.

Common problems we fix in Hoo St Werburgh

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

Common reasons people contact us include:

  • A bead that does not match the frame
  • Gaps between the frame and the inside reveal
  • Cracked sealant at the sill ends
  • Hard, cracked sealant around windows

If you let a flat or house near Gillingham (Kent) station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Choosing a sealant specialist

How the job changes by surface

Patio & French doors

Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that without cracking.

Timber windows & doors

Where timber has rotted at the joint, it needs repairing first. We’ll point out any rot we find, as a joiner will need to deal with it.

How to look after the new joints

Once the sealant has cured, a few habits help it last:

  • Keep timber frames painted
  • Do not paint over the silicone
  • Keep solvents and bleach off the sealant
  • Clean frames with a soft cloth and soapy water

Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.

A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.

Should I try it myself first?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Hoo St Werburgh questions

Will you come out to Hoo St Werburgh?

Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Does the coastal weather in Hoo St Werburgh affect outside sealant?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

How much does window mastic cost in Hoo St Werburgh?

Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email with a short description of the job.

What sealant do you use?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

How many windows can you do in a day?

The work takes most of a day for a typical house, less for a few frames. Access and the amount of old mastic make the biggest difference.

Is there any odour?

Possibly a little. It fades as the sealant cures.

I’m a tenant. Can you help?

Of course. Ask your landlord first, and we can send them the quote if that helps.

Is the work guaranteed?

Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.

Frames and glazing around Hoo St Werburgh

Hoo St Werburgh is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. With historic houses such as Restoration House (about 3.6 miles south-west) nearby, there’s older building stock in the area around Hoo St Werburgh as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

Schools such as Hoo St Werburgh Primary School and Marlborough Centre are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of St Werburgh, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How the visit works

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. A visit to Hoo St Werburgh is planned like any other: the time, the access and where to park are agreed in advance. 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. 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. Finally we tidy up and check each joint.

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
