Signs your windows and doors need replacing

Not every old window needs to go. Some faults can be fixed, and some mean the frame has had its day. Here is how to tell the difference.

Faults we can often repair:

• Mist between the panes. We swap the sealed unit and keep the frame.
• A stiff or broken handle, hinge or lock.
• Worn rubber seals that let in a draught.
• A door that has dropped and catches on the frame.

Signs the whole frame should go:

• Soft, rotten timber at the sill or bottom rail.
• Warped or cracked uPVC that will not close tight.
• Old single glazing or very early double glazing.
• Frames that no longer meet fire escape or safety rules.

On survey we check each window and door and tell you which ones need work. We never push a full swap if a repair will do the job. If only a few windows are past saving, we can replace those and fix the rest, then match the look so the house still reads as one.

Choosing frames that suit local homes

The right frame depends on the age and style of the house. Period homes often look best with timber or timber-look sash windows. Post-war and modern homes suit casements in white or coloured uPVC. Aluminium works well on extensions and modern builds where you want slim frames and big panes.

Our uPVC windows are the most popular choice. They are warm, need little upkeep and come in many colours and wood-grain finishes. If you live on a street with a set look, we match the style of the original windows so your home still fits in.

Glass that keeps in heat and keeps out noise

All our sealed units are A-rated as standard. They use low-E glass, an argon gas fill and warm-edge spacer bars. Together they cut heat loss and help stop condensation on the inside of the glass.

Homes near main roads or rail lines can add acoustic glass. Ground floor windows can have laminated glass for extra security. South-facing rooms can have solar control glass to keep them cooler in summer. We talk through each option on the survey and only suggest what your home needs.

Doors, conservatories and roof glazing

Windows are only part of the picture. Many homes in One Tree Hill get a new front door at the same time, so the whole front of the house matches. Composite doors are a popular choice. They are thick, strong and hold their colour, and they come with multi-point locks as standard.

At the back of the house, French doors, sliding doors and bifolds open up the garden. Wide openings may need a new lintel, which we check on survey. If you have an old conservatory that is too hot in summer and too cold in winter, a new roof can make it a room you use all year.

Skylights are a good way to bring light into dark rooms, loft rooms and flat-roof extensions. Roof windows suit pitched roofs. Lanterns and flat rooflights suit flat roofs. Sun tunnels can light a hall or landing where there is no room for a full window.

We can price these items on the same visit, so you get one survey and one quote for all the work. If you would rather do the work in stages, we can split the quote to match.

Planning, regulations and sign-off

Most like-for-like window and door swaps on a house do not need planning permission. Flats, listed buildings and homes in conservation areas may need consent. Building control in the area is handled by Lewisham Council. We tell you on survey if your home is likely to need approval, and we can help with drawings and product details.

All our work meets Building Regulations, including Part L for heat loss. We are registered with FENSA, so we can self-certify the job. You get a certificate when the work is done. Keep it safe, as you will need it when you sell.

Why use a local installer

A local team can get to you quickly and knows the area well. That helps in a few ways:

• Quicker surveys: We can often visit within days.
• Local know-how: We know which streets have extra planning rules and which house types need care.
• Easy aftercare: If a door needs adjusting or a lock needs a tweak, we are close by.
• Clear guarantees: Your work comes with a 10-year guarantee.

How a job runs, from survey to sign-off

We start with a free survey to measure up and talk through options. You get a written, fixed quote with each item on its own line. Once you agree, we make each window and door to measure. On fitting day we protect your floors, take out one opening at a time and clear away the old frames. We then check every handle and lock with you and send your certificate. Payment stages are set out in the written quote.

Frequently Asked Questions

Does double glazing cut outside noise?

Yes. A good sealed unit with tight seals stops a lot of road and street noise. Standard units help, and acoustic glass helps more. Acoustic units use panes of different thickness, or laminated glass, which block a wider range of sounds. The fitting matters too. Gaps around the frame let noise in, so we seal each window fully when we fit it.

How long do new windows and doors last?

Well-made uPVC, aluminium and composite products last for decades with simple care. Timber lasts just as long if it is painted every few years. Sealed units can mist up over time, but a single unit can be swapped without changing the frame. Locks and hinges should be oiled once a year to keep them working well.

Will new windows affect home insurance?

New windows with good locks can make your home more secure, which insurers like. Some insurers ask about the type of locks on doors and windows. Tell your insurer about the new locks and keep the paperwork we give you. We cannot promise a lower premium, as that is up to the insurer, but secure windows rarely count against you.

Can you match colours and finishes?

Yes. uPVC and aluminium come in a wide range of colours, including greys, black, cream and wood-grain foils. Many frames can have a different colour inside and out. Timber can be painted any colour you like. We bring samples to the survey so you can see them against your brick and in your own light.

What happens to the old windows?

We take them away on fitting day. Old uPVC frames can be recycled into new profile, and glass and metal parts can be recycled too. We clear the site before we leave, so you are not left with a skip or a pile of old frames in the garden. Waste removal is included in your quote.
