Window mastic for Hook homes and businesses

How we quote for window mastic

We quote each job individually. This is what makes a difference:

  • When we can work, for business premises
  • How much old sealant there is and how hard it is to remove
  • Access and height
  • The type of sealant required

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

What to tell us for a quote

Before you ask for a quote, have a think about:

  • Whether it has been sealed before
  • If it’s domestic, commercial or a hotel
  • Any access issues, like height or stairs
  • The address or postcode of the job

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

Window mastic in Hook

Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before work begins. To get one, ring 0345 464 0079 or email us with the number of frames and any access details for window mastic in Hook. Common call-outs are for sealant in the wrong colour for the frame and gaps where the sill meets the wall, across uPVC windows, aluminium frames and composite doors.

Many houses in smaller places like Hook have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.

All of our work is guaranteed for twelve months.

Window mastic in Hook: local notes

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Stratfield Saye House (about 4.8 miles north) are a reminder that the area around Hook has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

If you let a flat or house near Hook station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For site and facilities teams at buildings such as Hook Junior School, its window and door frames need their mastic kept sound, just like a home’s.

Hook is about 5 miles west of Fleet, in Hampshire. Every kind of property in Hook can book us for window mastic, old or new, large or small. The work is guaranteed for a year.

Looking after it afterwards

How long the joints last depends on use and care. Here’s what we suggest:

  • Ventilate rooms so frames don’t stay wet inside
  • Keep paint off silicone joints
  • Walk round the house once a year and look at the joints
  • Keep drainage slots and sill grooves clear

A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.

A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

Leave it or put it right?

Choosing the product is half the job. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In a smaller place like Hook, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Combining jobs into one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.

What we’re called out for in Hook

Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.

Keep an eye out for any of the following:

  • Untidy mastic left by window fitters
  • Gaps where the sill meets the wall
  • Damp patches on the reveal after heavy rain
  • Mastic that has split away from the wall

If you live in an older home near St John the Evangelist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Before you book anyone

  • What the cure time is
  • How the joint is cleaned and prepared
  • Whether you can choose the colour
  • Are they insured?

10 questions to ask before booking

Common questions in Hook

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

Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.

Is Hook in your area for window mastic?

Yes, Hook is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we will give you a clear price.

Will new mastic stop draughts?

Often, yes. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.

How long before the joint can be used?

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

Can you reach windows above the ground floor?

Normally, yes. We plan safe access before the job.

Will there be a smell?

Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.

Can I paint over the new sealant?

Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.

Are you an approved applicator?

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.

Should I try it myself first?

A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

The process

There is not much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a morning for a couple of windows and a door from start to finish. Parking around Hook is generally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. Each frame is looked over and we agree which ones need resealing.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Deep gaps get closed-cell backing rod to set the depth.
  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.

Getting ready for the visit

  • Tell us about any water getting in
  • Clear the area around the work
