Windows and doors in Woodmancote

Woodmancote is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. 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.

Managing a site like Bourne Community College? Then its window and door frames need their mastic kept sound, just like a home’s. Homes close to Woodmancote Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Southbourne station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Woodmancote is about 4 miles east of Havant, in West Sussex. Woodmancote gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee.

Leave it or put it right?

Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Around Woodmancote, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

What you get with us

  • More than 20 years in sealant work
  • Colour picked to suit the job
  • Neat joints and a tidy finish
  • Colour agreed with you before any work starts

Surface by surface

uPVC windows

uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.

Window sills

Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.

Looking after it afterwards

A little care helps the new joints last. We recommend:

  • Wipe condensation off the frames
  • Clean frames with a soft cloth and soapy water
  • Don’t use solvent cleaners on the joint
  • Look round the frames every year or so

Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.

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

How we quote for window mastic

Your quote is based on your job. We look at:

  • Any mould that needs treating
  • The number and length of the joints
  • How many rooms, windows or areas are involved
  • The product the joint needs

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear price before we start.

What we need to know

Before you ask for a quote, have a think about:

  • The rough size of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • The type of property
  • If someone has resealed it before

Every job is quoted individually, so the first step is telling us about yours. Simply ring 0345 464 0079 or send us an email and describe the job.

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Some sealant jobs are within reach of a careful DIYer, 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.

Questions from Woodmancote

Is Woodmancote within the area you cover?

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 Woodmancote affect outside sealant?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Can you work on commercial sites?

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

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.

Do you work on first-floor windows?

Usually, yes. We plan safe access before the job.

How do I get a quote for window mastic in Woodmancote?

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.

Can you do several jobs on one visit?

Yes, we can. More than one area can be quoted together.

Will you leave a mess?

Very little: the area around the joints is protected first, and we tidy up before we go.

How it works

Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. In a small place like Woodmancote, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  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. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. Finally we tidy up and check each joint.

Getting ready for the visit

  • Mention any tricky access
  • Mention any leaks or damp you’ve noticed
  • Let us know about parking restrictions
