What affects the quote in The Holt

You will get a clear quote before work begins. It’s based on:

  • How many rooms, windows or areas are involved
  • Mould in or behind the old joints
  • How easy the joints are to reach
  • Which sealant suits the joint

The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.

Asking for a quote

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

  • Whether it has been sealed before
  • The problem you’ve noticed
  • Access, such as stairs, a lift or height
  • Photos by email, if that’s easy

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.

How the job changes by surface

Window sills

Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.

uPVC windows

Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.

What sealant work cannot fix

We won’t take on work that won’t last, so here’s what sealant cannot put right:

  • Broken hinges, locks or handles
  • Soft or decayed wood in the frame
  • A failed sealed unit that has misted up

If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

Joints and surfaces we work on

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

Signs you need window mastic in The Holt

Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, so it comes away long before its time.

Any of these means the joints need attention:

  • Gaps between the frame and the inside reveal
  • Damp patches on the reveal after heavy rain
  • A bead that does not match the frame
  • Old mastic that has gone black or come away

For landlords with property near Wargrave station, renewing tired window mastic between tenants heads off draught and damp complaints.

What to look for in a quote

  • What the cure time is
  • Are they insured?
  • How the joint is cleaned and prepared
  • How the colour is chosen

10 questions to ask before you book

Common questions in The Holt

Will you come out to The Holt?

Yes. The Holt is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

I let a flat near Wargrave station. Can you help?

Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.

Which products do you use?

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.

Is there any odour?

Some sealants have a smell while they cure. Opening a window helps.

Will resealing my frames help with draughts?

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’ll say so.

Do you hold any approvals?

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

How long will my window job take?

A few frames take a few hours, while a whole house takes longer. We confirm the timing with your quote.

Is it OK to seal over old sealant?

No. The old sealant always comes out first, so the new sealant bonds properly.

Landlords, agents and businesses in The Holt

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

If you manage several properties in or around The Holt, several properties can go on one quote. Just tell us the addresses and what each one needs, and pictures by email help.

The process

There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of frames, longer for a whole house for a typical job. Somewhere like The Holt 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. We remove the old mastic and clean the frame edge and wall.
  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. Every joint is tooled smooth and checked before we leave.

Preparing for the visit

  • Mention if the joints have been sealed before
  • Let us know about parking restrictions
  • For business premises, tell us about site rules or sign-in

Should I try it myself first?

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.

Window mastic in The Holt: local notes

With historic houses such as Harleyford Manor (about 3.9 miles north) nearby, there’s older building stock in the area around The Holt 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Harleyford Manor, about 3.9 miles north, is one of the historic houses in the wider area around The Holt. If you look after a building such as Robert Piggott CofE Infant School, the mastic around its windows and doors needs looking after like any other building’s.
