Window mastic for Remenham Hill homes and businesses

For landlords and businesses

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Window mastic in Remenham Hill

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 deep gaps get backing rod first. The sealant then grips the two sides it should. If you are dealing with cracked sealant at the sill ends and gaps between the frame and the inside reveal, we can put it right, whatever the surface.

Mastic can only go onto a dry, clean joint, so window work in Remenham Hill is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

There’s a 12-month guarantee on every job, large or small.

What happens on the day

The work is kept neat and contained to the joints we are treating. The job usually takes a morning for a couple of windows and a door, and we explain the cure time before we leave. Somewhere as small as Remenham Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First, we go round the frames with you and agree the list.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Where the gap is deep, backing rod goes in first.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. Every joint is tooled smooth and checked before we leave.

Before we arrive

  • Plan for the work area to be out of bounds to pets and children
  • For business premises, tell us about site rules or sign-in
  • Tell us about access, such as stairs, a lift or high-level joints

How the job changes by surface

Aluminium frames

Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. Neutral-cure sealant is the safe choice.

Patio & French doors

The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.

Remenham Hill homes and the weather

With historic houses such as Greenlands (about 1.7 miles north) nearby, there’s older building stock in the area around Remenham Hill 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Homes close to Church of St Nicholas include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as Rupert House School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Henley-On-Thames station, renewing tired window mastic between tenants heads off draught and damp complaints.

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before you book.

Remenham Hill: your questions answered

Do you work for landlords with property near Henley-On-Thames station?

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.

Do you cover Remenham Hill for window mastic?

Yes. We work across London and the South East, and Remenham Hill is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job.

Can resealing stop a draught around my window?

Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

When is the sealant fully cured?

That depends on the sealant used, so please follow the time we give you when we finish.

Which products do you use?

Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we’re using and why.

Why it’s worth doing now in Remenham Hill

Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Older cottages and farmhouses around Remenham Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

Why us?

  • Full insurance on every job
  • A sealant colour to suit the surroundings
  • Sanitary silicone with an anti-fungal additive in wet areas
  • Approved under the ARBOMaster scheme

How we quote for window mastic

For a quick quote, just ask. The main things that affect it are:

  • The number and length of the joints
  • Mould in or behind the old joints
  • When we can work, for business premises
  • The product the joint needs

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

Helping us quote

Photos help, but a description is a good start. Try to tell us:

  • Whether it’s a home or a business
  • Whether it has been sealed before
  • What the problem is, such as mould, gaps, leaks or cracking
  • Pictures of the joints, sent by email

Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand.

Can I do it myself?

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.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
