When it isn’t the sealant

In fairness, some problems need a different trade:

  • Penetrating damp from a failed cavity tray or render
  • Worn gaskets, brush seals or a door that has dropped

Window mastic for homes and businesses in Rushmoor

Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We are often asked to deal with old mastic that has gone black or come away and cold air getting in at the frame edge, across aluminium frames, uPVC windows and window sills.

Somewhere as small as Rushmoor, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

Windows and doors in Rushmoor

Historic houses like Farnham Castle (about 4.8 miles north-west) are a reminder that the area around Rushmoor has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Farnham Castle, about 4.8 miles north-west, is one of the historic houses in the wider area around Rushmoor, and older homes nearby need a sealant that suits their walls.

Looking after it afterwards

To keep the joints looking good and working properly:

  • Walk round the house once a year and look at the joints
  • Do not aim a pressure washer at the joints
  • Wash the frames with mild soapy water
  • Repaint timber before it’s bare

On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.

Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.

Landlord and commercial work in Rushmoor

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.

What we do, step by step

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 anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Rushmoor needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Each frame is looked over and we agree which ones need resealing.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Where the gap is deep, backing rod goes in first.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. We tool each bead neatly and check every joint is closed.

How to prepare

  • Mention any parking rules near the property
  • Let us know about earlier repairs to the joints
  • Keep children and pets away from the work area

Common questions in Rushmoor

Do you cover Rushmoor for window mastic?

Yes. Our work covers London and the South East, and Rushmoor is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.

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

Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Can you do several jobs on one visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit.

Do you guarantee window mastic?

Yes. Each job is covered for 12 months, inside or out.

What does window mastic cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.

Is there any odour?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Can new window sealant be painted?

Silicone generally won’t take paint. Let us know beforehand, and we’ll use a paintable product where it suits.

Are you an approved applicator?

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

What we’re called out for in Rushmoor

Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.

Look out for these signs:

  • Water coming in at the bottom corners of a door
  • Cracked or shrunken mastic around the frame
  • Gaps between the frame and the inside reveal
  • Gaps where the sill meets the wall

For landlords with property near Farnham station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What your quote should include

  • Is the old sealant removed completely?
  • Are they insured?
  • When the joint can take water or movement
  • How the joint is cleaned and prepared

Choosing a sealant specialist

Why act early in Rushmoor

The work is quick compared with the damage it prevents: it takes a morning for a couple of windows and a door. Wait for damp to appear and there may be plaster and decorating to sort out too. Around Rushmoor, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

Why us?

  • Tidy, careful work
  • More than 20 years in sealant work
  • Quality sealants from Arbo and Everbuild
  • Colour picked to suit the job

What the job involves on each surface

Composite doors

An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.

Timber windows & doors

Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
