Landlord and commercial work in Hinksey Hill

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.

Window mastic in Hinksey Hill, done properly

Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Common call-outs are for black, perished sealant on frames and sealant in the wrong colour for the frame, on composite doors, patio & French doors and window sills.

In a village or hamlet like Hinksey Hill, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.

All our work comes with a one-year guarantee.

DIY sealant or a professional job?

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

FAQs for Hinksey Hill

Do you work for landlords with property near Oxford station?

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

Is Hinksey Hill in your area for window mastic?

Yes, Hinksey Hill 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 will give you a clear price.

Which products do you use?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

What should I tell you?

A short description and the location, with photos by email if possible. If we need more, we’ll ask.

How many windows can you do in a day?

It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.

Is the new sealant paintable?

Not normally, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.

Where are you based?

We work from Crawley. Our applicators cover Hinksey Hill, along with the rest of our area.

Will resealing my frames help with draughts?

In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.

How we quote for window mastic

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

  • Whether old sealant or filler has to be cut out
  • The type of sealant required
  • The number of rooms or windows
  • Whether there’s mould to deal with

Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Helping us quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • The type of property
  • Where the job is, and your postcode
  • If someone has resealed it before
  • What’s wrong with the joints now

There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or drop us an email.

Windows and doors in Hinksey Hill

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. Historic houses like Holywell Manor (about 2.3 miles north) are a reminder that the area around Hinksey Hill has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

For an older house near a landmark such as Church of St Lawrence, 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 New Hinksey Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Signs you need window mastic in Hinksey Hill

Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.

Look out for these signs:

  • Whistling draughts around closed windows
  • Hard, cracked sealant around windows
  • Rushed sealant from a window installation
  • Cracked internal joints between frame and plaster

If you let a flat or house near Oxford station, renewing tired window mastic between tenants heads off draught and damp complaints.

What to look for in a quote

  • Is the old sealant removed completely?
  • Is VAT in the price?
  • How much experience the applicator has
  • What preparation is included

How to choose a mastic man

What we cannot put right

We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:

  • Rotten timber, which needs a joiner first
  • Penetrating damp from a failed cavity tray or render
  • Worn gaskets, brush seals or a door that has dropped

If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

What the job involves on each surface

Window sills

Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.

Timber windows & doors

Soft or rotten wood cannot be sealed successfully. We’ll point out any rot we find, as a joiner will need to deal with it.

How the visit works

There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes most of a day for a typical house, less for a few frames in most cases. Somewhere like Hinksey Hill 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. We start by checking each window and door with you.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. Deep gaps are filled with backing rod to set the depth.
  4. A flexible, weatherproof sealant is applied in a colour to suit the frame.
  5. We clear up and check every joint is fully closed.

Getting ready for the visit

  • Tell us if parking is tricky
  • Move anything stored near the joints
  • On commercial sites, let us know about site rules

Ask for a quote
