Window Installers

Many of our projects involve removing existing windows and installing new replacements.

Homeowners may decide to replace their windows because the existing frames are ageing, difficult to operate or no longer provide the appearance they want. Others choose replacement windows as part of a wider renovation or to improve the thermal performance of their home.

Our replacement window installation service begins with an assessment of the existing openings and discussion about the type of windows required.

Once the new windows have been manufactured to the agreed specification, our installers can remove the existing units and prepare the openings for the replacements.

The new frames are then positioned, fixed, glazed and sealed before the opening sections and hardware are checked.

South Lakes Windows supplies and installs a wide range of UPVC windows.

UPVC remains a popular choice for replacement windows because it can be used across many different house styles and requires relatively little routine maintenance.

The available designs include casement windows, flush windows, sliding sash windows, tilt and turn windows, bay and bow windows, French windows and fixed windows.

Colour and woodgrain finishes can also provide alternatives to standard white frames.

Our UPVC window installers can replace existing windows or install new units as part of an extension, conservatory, orangery or other building project.

South Lakes Windows also provides professional timber window installation.

Timber windows can work particularly well with cottages, farmhouses, Victorian and Georgian properties and homes where the appearance of traditional joinery is important.

We supply timber window ranges from Bereco, including Contemporary, Traditional and Heritage options.

The selected style can incorporate details suited to the property, including glazing bars and traditional window proportions.

Our timber window installers understand that the relationship between the new frame and the existing building needs careful consideration, particularly on older properties.

This becomes especially important when installing windows into traditional stonework or replacing existing period windows.

For homeowners looking for slimmer frames and larger areas of glass, South Lakes Windows supplies and installs aluminium windows.

Aluminium can be particularly suitable for modern homes, extensions and properties with large glazed areas. Slim sightlines can increase the visible glass area while creating a clean external appearance.

A wide range of finishes can be considered, including colours suitable for coordinating with aluminium entrance doors, sliding doors and bi-folding doors.

Aluminium windows can also be combined with fixed glazing to create larger window arrangements for kitchens, living rooms, extensions and garden-facing elevations.

Our window installers can fit aluminium products as replacement windows or as part of a new home improvement project.

South Lakes Windows provides sash window installation for traditional and period properties as well as newer homes where this style is preferred.

Vertical sliding sash windows have a distinctive appearance, with upper and lower sashes moving vertically within the frame.

We offer several sash window options, including ByGone UPVC, Authentic UPVC and timber windows from the Bereco Heritage, Traditional and Contemporary ranges.

Features such as sash horns, glazing bars and appropriate frame proportions can help new windows relate more closely to the architecture of an older property.

Modern glazing and locking systems can then be incorporated according to the selected product.

Bay and bow windows require particular attention during measurement and installation because several window sections need to work together as one arrangement.

A bay window normally projects from the property using a series of angled sections. A bow window creates a more curved appearance using multiple window units.

Replacement work needs to consider the existing structure as well as the new frames.

Some bay windows can form part of the support arrangement above them, so structural requirements need to be established before the existing units are removed.

Our team can survey the existing window and determine the appropriate installation approach before replacement work begins.

The majority of modern replacement window projects involve double glazed windows.

A double glazed unit uses two panes of glass separated by a sealed cavity. The complete window specification, including the frame, glass, spacer and seals, contributes to its thermal performance.

South Lakes Windows can also provide different glazing options according to the room and property.

These can include obscure glass for privacy, laminated glass where appropriate, decorative glazing and acoustic specifications for homes affected by external noise.

We can also discuss triple glazed windows where the additional pane and different glazing construction suit the requirements of the project.

Installing replacement windows in an older property often requires more consideration than fitting windows into a modern house.

South Lakes Windows works with cottages, farmhouses, stone-built houses, Victorian properties and other traditional homes throughout Cumbria, Lancashire and adjoining Yorkshire.

Existing openings may vary in size and shape, while the original architecture can influence which replacement window styles are appropriate.

Material, frame proportions, glazing bars, opening arrangements and colours can all affect the finished appearance.

Timber Heritage and Traditional windows may suit some properties, while sliding sash or traditionally styled UPVC windows can provide alternatives elsewhere.

Our team can assess the building before recommending suitable window options.

The South Lakes and surrounding areas contain many conservation areas where alterations to windows can require additional consideration.

A conservation area does not automatically prevent window replacement, but planning controls and local requirements may influence what changes are acceptable. Some properties may also be affected by an Article 4 Direction that restricts certain permitted development rights.

Listed buildings are subject to separate controls, and listed building consent may be required before existing windows are altered or replaced.

South Lakes Windows has experience working with properties where planning and conservation considerations are important.

Our team can help identify these issues during the early stages so they can be considered before the final window specification is agreed.

Our window installers also work on home extensions, conservatories and orangeries.

These projects provide an opportunity to design the window arrangement around the intended use of the new room rather than working with existing openings.

A kitchen extension may use large aluminium windows and fixed glazing to increase garden views. A traditional orangery may use more regularly spaced windows with glazing bars. A home office may require a combination of natural light, ventilation and privacy.

Because South Lakes Windows provides design, building, window, door and glazing services, these different elements can be planned as part of the wider project.

Accurate measurement is a key part of replacement window installation.

Before windows are ordered, the existing openings need to be surveyed so the replacement products can be specified correctly.

This involves more than recording the basic height and width.

The installer may need to consider the construction around the opening, internal and external finishes, sill arrangement and how the existing window sits within the wall.

Bay windows, shaped windows and older properties can require additional measurements because the openings may be more complicated.

A detailed survey reduces the risk of discovering avoidable problems once installation begins.

Window replacement usually requires the existing frames and glazing to be removed before the new units can be fitted.

Our installers work carefully around the surrounding opening, taking account of internal and external finishes.

Once the old window has been removed, the accessible opening can be checked before the replacement frame is installed.

The new window is positioned and fixed according to the requirements of the product and building. Glazing, opening sashes and hardware can then be fitted or checked as appropriate.

The perimeter is finished and sealed before the operation of the window is tested.

Installation is not complete simply because the window is in the opening.

Opening sections should operate correctly, locks and handles need to function as intended, and the finished installation should be checked.

Casement windows should open and close correctly. Tilt and turn windows need to operate through their different opening positions. Sliding sash windows should move correctly within their frames.

Our installers can also explain the normal operation and care of the products fitted.

Following installation, South Lakes Windows provides an after sales service, giving customers an ongoing point of contact for work and products supplied by us.
