Window mastic for homes and businesses in Clifton Reynes

Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done.

In a village or hamlet like Clifton Reynes, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Why it’s worth doing now in Clifton Reynes

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’s needed. If we find failed glass units or worn seals, we will tell you. Older cottages and farmhouses around Clifton Reynes can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

For landlords and businesses

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

How it works

We keep the work tidy and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. Somewhere as small as Clifton Reynes, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. First, we confirm safe access to each frame.
  2. Old, cracked mastic is removed completely.
  3. The surfaces are cleaned and left dry, and primed where the sealant calls for it.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. The joint is shaped to shed water and the area tidied.

Preparing for the visit

  • Tell us about any water getting in
  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know about parking restrictions

Getting a quote

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Advice

Window mastic in Clifton Reynes: local notes

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Turvey Abbey (about 2.7 miles east) nearby, there’s older building stock in the area around Clifton Reynes as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

Homes close to Parish Church of St Mary include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. In and around Clifton Reynes, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Questions from Clifton Reynes

What guarantee comes with window mastic in Clifton Reynes?

Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.

Is Clifton Reynes in your area for window mastic?

Yes, Clifton Reynes is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.

Is there any odour?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

What do you put in the joint?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Does someone need to be in?

It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.

Do you work for landlords and businesses?

Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.

Where are you based?

Mr Mastic is based in Crawley. Our applicators cover Clifton Reynes.

Can you do the inside joint as well?

Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.

What we can’t put right

Sealant is not the answer to every problem, and we will tell you before we start. Sealant will not put right:

  • Condensation trapped between the panes
  • A door that needs adjusting, rehanging or new seals
  • A sash or casement that will not close properly

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.

Where we work in Clifton Reynes

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

How to look after the new joints

No joint lasts for ever, but care makes a real difference. Our tips:

  • Do not paint over the silicone
  • Wash the frames with mild soapy water
  • Keep timber frames painted
  • Do not use solvent cleaners on the joint

On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.

Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.

Quotes for window mastic in Clifton Reynes

You will get a clear quote before we start. It’s based on:

  • The number and length of the joints
  • The number of rooms or windows
  • The type of sealant required
  • Access and height

We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

What we need to know

To make quoting easier, please include:

  • Photos by email, if that is easy
  • The address or postcode of the job
  • If it’s domestic, commercial or a hotel
  • How many joints, rooms or windows are involved

If you are in Clifton Reynes and need window mastic, phone 0345 464 0079 or drop us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.

Should I try it myself first?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
