How do I know if I need to repair or replace my windows?

If your window problem is minor then you might be able to repair the window yourself, however, it is always best to have the window looked at by an expert to determine if it can be fixed or will need a replacement window.

You can tell if you need new or replacement windows by checking through these statements:

• My windows don’t open and close easily. In this instance, the window frames could have warped, started to rot, or maybe the wrong size.
• My windows are drafty. This issue occurs when a window doesn’t shut properly, the locking system no longer works, or the windows are single glazed. Windows with double glazing are significantly more energy-efficient than single glazed windows, so you could end up saving quite a lot of money on your heating bills by switching.
• You can hear outside noise from inside and the window is shut. This is usually a sign that the windows are very old and will need replacing.
• Your window is leaking. This is a sign that the seals around the glass have gone, replacing existing windows with new double glazed windows will be the most cost-effective option.
• My windows are over 15 years old. We always recommend asking an expert if an old window is still in good enough condition or if a replacement double glazed window will be needed.

What is double glazing and how does double glazing make my home more energy efficient?

Double glazing works by trapping air between two panes of glass, this provides a barrier and helps insulate the space, regulating the interior temperature and keeping the weather outside at bay.

Energy efficient double glazed windows consist of a frame (timber, aluminium, PVC-U or composite) into which two sealed glass units are fitted, according to the style of the window. Energy efficient glazing is rated according to its ability to reduce the amount of heat that can pass through the window. Our double glazed windows are A+ rated and you could see your energy bills, heat loss and the amount of condensation reduce.

How much does double glazing cost?

Every home is different and this means it is hard to give an upfront cost of installing double glazing as it depends on the individual project. The cost of double glazed windows depends on different elements including style, size, fitting costs, non-standard shapes, the handles, accessories and what glass detailing options you choose.

Will fitting new windows add value to my home?

Replacing your old windows with double glazed windows can add value to your property, double glazed windows are an essential decision factor to many house hunters. Most window installations will cost around 2-3% of the home’s value (dependant on style, size and number of windows required) and although this is is an upfront cost, that can be paid off over a period of time via our finance options, in the long run replacing your old windows with new uPVC windows will increase the property’s value and effectively pays for itself in the long run.

Do you offer payment plans/finance on windows?

We work with a range of providers to offer finance/loan options that help you spread the cost of your replacement uPVC windows. Full information around the loan and finance options on windows can be found on our finance page.

How do you make your double glazed windows secure?

We understand that secure windows are essential in any home, and therefore all our uPVC double glazed windows are designed and built with security in mind.

Double glazing by its nature offers greater security than single glazing as there are 2 panes of glass, which makes it harder to break. All our secure windows also feature the industry-leading blade locking system from Yale, which has been tested to the equivalent of at least 30 years of heavy use. The pinnacle of lock technology means double glazed windows with Yale Blade Locking are 3x more secure than standard window locking systems.

What colours do double glazed windows come in?

Plain windows are a thing of the past, currently, we offer a beautiful selection of 9 standard colours for our uPVC replacement windows. UPVC can be customised with almost any RAL window colour of which there are over 1600. You can choose your favourite colour and create a bespoke coloured uPVC window.  If you are looking for a more traditional finish then our woodgrain foils come in a range of colours including Agate Grey, Black Storm (Slate), White, Grey including Anthracite Grey, Rosewood, Cherrywood, Irish Oak, and Cream.

Do coloured uPVC windows cost more than white uPVC windows?

Based on a like-for-like window, opting for a coloured UPVC window instead of a traditional white window can cost a little more, the amount will depend on the size and style of the windows needed. uPVC as a material is much cheaper than the alternatives, so opting for coloured uPVC is actually cheaper than replacing the window with timber or aluminium. uPVC is known as a durable material, will reduce condensation, noise as well as keeping your home looking great and well worth considering for your next home improvement.

Which are better wooden windows or uPVC windows?

Wooden window frames can suffer easily from rot and decay and can be hard to treat and unless you look after them you will find they need replacing more frequently than modern uPVC windows which are more durable, hardwearing and low maintenance.

uPVC windows are cheaper than hardwood timber, and all uPVC windows are energy rated with Building Regulations, so are extremely thermally efficient. Another advantage to uPVC windows, they never need painting and will only need a wipe down with a damp cloth once every couple of years.

Do your double glazed windows come with a guarantee?

First Home Improvements guarantee all our double glazed windows under a 12-year warranty. The locks on all our windows are supplied by Yale’s new revolutionary Blade Lock which are also included as part of the 12-year warranty.

Will any window styles fit in my home?

Choosing window styles that suit your home is essential, however, there are limitations on certain properties and types of windows that will fit. If your home is a listed building or within a conservation area there will be restrictions and you should seek advice before making any changes. Casement windows can be custom built to fit any size; however, Sash windows will fit into certain specifications, it is best to organise a free consultation with our local experts to decide which style of window will suit your property.

Will I need to re-decorate after my windows are fitted?

Our window installers take the best care to minimise the impact of their work, to avoid any damage to walls or floors when installing your windows. On the odd occasion, there can be some minimal painting required.

Should double glazed windows get condensation?

It is not unusual to have condensation on the outside of new double glazed windows; in fact, it’s perfectly normal. What is happening is that the window is blocking the heat from inside your home from reaching the outside of your home thus the outside windows are cooler and condensation happens.

If condensation is appearing on the inside of your windows, then you might have other issues, look out for any damage to the seals around the windows as this could allow water in. Try to keep a gap of 100mm between furniture and the wall in order to allow circulation, and ensure your washing isn’t drying in a small closed-off area. If you have a question about the condensation on your First Home Improvement double glazed windows then please contact us and we will be happy to organise a visit and survey your windows.
