Window mastic for Great Bromley homes and businesses

Window mastic in Great Bromley, done properly

Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We’re often asked to deal with draughts coming in around windows and doors and rushed sealant from a window installation, across uPVC windows, aluminium frames and timber windows & doors.

Outdoor sealant needs dry, clean surfaces, so work on frames around Great Bromley is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

Our work is backed for twelve months, in Great Bromley and everywhere else we cover.

Windows and doors in Great Bromley

With historic houses such as Castle House (about 4 miles north) nearby, there’s older building stock in the area around Great Bromley 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. 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.

If you let a flat or house near Alresford station, renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to Church of St George include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY sealant or a professional job?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

Why deal with it now?

A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Older cottages and farmhouses around Great Bromley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Why book with us

  • An ARBOMaster approved applicator
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Rated 4.9 stars on Google
  • A sealant colour to suit the surroundings

Great Bromley questions

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

Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.

Is Great Bromley within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Can you do upstairs windows?

Yes, if safe access is possible. Higher or awkward frames may need extra access, and we will confirm what’s needed.

Where are you based?

We are a Crawley-based firm. We work across South East England, London and Scotland.

Is the new sealant paintable?

Not generally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.

Are you fully insured?

Yes. We’re fully insured.

Do you seal inside as well as outside?

Yes. Draughts often come through the inside gap too, so it can be worth sealing both.

Are you ARBOMaster approved?

Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

What the job involves on each surface

Patio & French doors

Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.

Composite doors

If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.

Work for landlords, hotels and businesses

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.

Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.

What happens on the day

Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Great Bromley, 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. Next the failed sealant is cut away and the joint cleaned.
  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. Every joint is checked before we leave.

How to prepare

  • For business premises, tell us about site rules or sign-in
  • Mention any leaks or damp you’ve noticed
  • Move anything stored near the joints

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, phone 0345 464 0079 or drop us an email.

Quotes for window mastic in Great Bromley

  • The number and length of the joints

  • Mould in or behind the old joints
  • The product the joint needs

Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

What we need to know

To make quoting easier, let us know:

  • Where the job is, and your postcode
  • The type of property

When to call us in Great Bromley

Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.

The most common problems we see are:

  • Damp patches on the reveal after heavy rain
  • Sealant in the wrong colour for the frame
  • Cracked internal joints between frame and plaster
  • Untidy mastic left by window fitters

For site and facilities teams at buildings such as St George's Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What to look for in a quote

  • Are they insured?
  • Whether the sealant suits the joint
  • Whether they seal over old material or remove it
  • When the joint can take water or movement
