uPVC French Windows in Portsmouth

French windows are paired glazed doors, usually connecting a room to a garden. Before seeking Portsmouth quotes, distinguish replacing an existing doorset from converting a window.

Tell us about the opening you have in mind and Hampshire Windows can pass your enquiry to independent installers covering Portsmouth, Hampshire. Where installers have capacity, up to four may get in touch with a quote. It costs nothing to enquire and there is no obligation.

Two Very Different Jobs

Swapping an old pair of French doors or a worn sliding patio door for new French windows is fairly straightforward. The existing opening is reused, so there is little building work.

Turning a window into French doors is a bigger job: the brickwork below the window is cut down to floor level, the lintel above must be adequate for the new opening, and a threshold has to be formed. Radiators, skirting and floor finishes may need altering, and this part of the work is sometimes done by a builder rather than the window installer.

Points to Raise for Your Portsmouth Project

• Whether the doors should open inwards or outwards
• What the doors open onto: patio, lawn, deck or a narrow side return
• Whether you want a low threshold for easier access
• Whether you would like fixed or opening side panels
• For an upstairs pair, whether you want a glass or railing balustrade

If you choose a low threshold, ask how water will be kept out, especially on exposed elevations that take the brunt of wind-driven rain.

Getting the Specification Right in Portsmouth

Ask which leaf opens first and how the doors will be held safely when in use. Floor levels, curtains and furniture affect the layout just as much as the view outside.

The Installation Process

1. Site visit: the installer measures the opening, checks floor levels inside and out, and looks at the wall above.
2. Specification: you confirm the opening direction, threshold, glass, colour and any side panels.
3. Building work: where a window is being converted, the brickwork below is cut out and the lintel checked or replaced.
4. On the day: the doorset is fixed, levelled, glazed and sealed, and the threshold weatherproofed.
5. Adjustment: both leaves are set to meet evenly and lock securely, and the installer shows you the locks and shoot bolts.

The threshold needs compatible weather seals and a drainage detail suited to the exposure. Glazing packers help stop the leaves dropping; the installer should adjust hinges, keeps and shoot bolts, then demonstrate both doors and locks.

Tell firms whether the ground outside your Portsmouth doors slopes towards the house. Any new steps, drain channel, radiator move or Juliet guarding should be described and costed separately.

French Window Costs in Portsmouth

The guide range for this service is £1,100–£3,500. The lower end covers a straightforward pair replacing old doors, while wider sets with side panels or coloured frames sit higher; Juliet guarding is a separate allowance. Converting a window can add building costs on top.

Check that the price covers the lintel, cutting out and making good, moving a radiator, the threshold, VAT and disposal of the old frames. These items vary a lot between quotes.

Consent to Check

Replacing existing French doors, or turning a rear window into French doors on a house, is usually permitted development. A new opening on the front of the house, in a flat, a listed building or a conservation area may need consent, and an upstairs Juliet balcony can raise privacy questions. Check with Portsmouth City Council before going ahead.

Replacement doors must meet Building Regulations for energy efficiency and safety glazing and can usually be self-certified by a competent person scheme installer. Enlarging or lowering an opening is structural work that may need building control, and Juliet balconies must meet the guarding requirements in Approved Document K.

Request Your Quotes

Start by saying where the doors will go and what they open onto. Hampshire Windows introduces enquiries and does not fit doors or windows. Businesses joining the network are asked for insurance details and references; check current documents and who will do any building work before appointing anyone.

These prices are planning allowances, not fixed quotations. Quantity, specification, access and additional work can take the total outside the range. Describe your project to request free quotes.

For eligible replacement work, confirm the installer’s scheme registration and certification arrangements. An appropriate building control approval route is another option; see the government guidance on competent person schemes. If the address lies within a national park, confirm which planning authority handles the property before ordering.
