Scope and approach

What you get

How warm and quiet it is around the window depends not only on the profile but also on the installation. The frame is fixed with anchors into the sound part of the wall, and the joint is filled with foam and protected with tapes inside and out.

In a renovation, the windows are replaced before skim coating and painting, because the reveals get damaged when the old ones are removed. We re-form the reveals, fit the interior window boards, and fit the external sills with a fall to the outside.

Technical detail: a three-layer installation joint

Foam insulates, but on its own it is not a seal. On the inside it is covered with vapour barrier tape, and on the outside with a tape that keeps rain out but lets vapour through, so the joint does not get damp.

  • Precise measuring of the openings for ordering the windows
  • Removal of the old windows with minimal damage to the walls, and carrying them off site
  • Installation plumb and true, with packers and anchors into the sound part of the wall
  • A three-layer installation joint – vapour barrier tape, foam and a protective tape outside
  • An internal window board and an external sill with a fall and sealed ends
  • Adjusting the sashes and hardware, and making good the internal reveals
When to call us

From the problem to the solution

The most common situations people call us about, and how we approach them.

Common problems

  • Draughts and cold around the frame, even though the windows are new
  • Condensation and mould on the reveals around the window
  • Sashes that rub or do not press evenly against the seals
  • Water getting in under the window sill when it rains
  • Exposed foam outside that crumbles after a few years

How we approach them

  • We fill the joint all the way round, with no voids in the foam
  • We cover the joint on the inside with vapour barrier tape, so it does not get damp
  • We install the frame true and adjust the hardware on every sash
  • We check how the external sill meets the frame and the wall, and seal the point where water gets in
  • We protect the foam on the outside with tape and cladding against sun and water

A good fit when

  • When you are replacing old timber windows that let in air and water
  • When the windows are ordered and you need proper installation
  • When you are doing a major renovation and the windows need replacing before skim coating
  • When the facade is about to be insulated and the windows need replacing first

Process

How the work runs

We organise the work around the specifics of the city and the property, planning access, logistics and stages.

  1. Site visit, measuring the openings and checking the wall around them

  2. Protecting floors and furniture, and removing the old windows

  3. Levelling, fixing with anchors and filling the joint with foam

  4. Applying the tapes over the joint and fitting the window boards and external sills

  5. Adjusting the sashes, finishing the reveals and cleaning

Price

What affects the price

The installation price is set after a site visit, because the size of the units, the removal and the finishing of the reveals differ on every job.

The final cost is confirmed after a site visit and once the window sizes are confirmed.

  • Number and size of windows and balcony doors
  • Profile type – PVC, aluminium or timber
  • Removal of the old windows and carrying out the waste

Questions and answers

Window installation in Varna: questions and answers

Before plastering, skim coating and painting, because the reveals get damaged when the old windows are removed. That way they are finished once, together with the rest of the walls.

No. Foam insulates, but it has to be protected – on the inside with vapour barrier tape, and on the outside with tape and cladding against water and sun. Otherwise it loses its properties over the years.

New windows are airtight, so moisture from cooking, bathing and breathing no longer escapes through gaps. Regular ventilation is needed, and if there is condensation only on the reveals, we check the installation joint.

The profiles, glazing units and hardware carry the manufacturer's warranty. We are responsible for the installation – with a written 2-year warranty.

One window is usually replaced in a few hours, and a whole home in a day or two, depending on the number and size of the units. Finishing the reveals is a separate stage.

Book a site visit and we will measure the openings for your new windows.

You will receive a written quote for removal, installation, the tapes and finishing the reveals.
