We appreciate that you may have a lot of questions regarding our products, which we’ve aimed to cover below. If there are any other queries you have, please do not hesitate to contact us.

How much is an average window?2018-09-17T11:30:46+00:00


Have you any installation referrals?2018-09-18T14:48:29+00:00

Many of our clients want to look at what others opinions of us are and we embraced this by becoming a member of All Checked. Our clients have the opportunity of leaving an online review of how they score us, further details available on the site.

Are you expensive?2018-09-17T11:29:48+00:00

At Realistic, it has always been our goal to provide quality accredited products, excellent installation, good service and long term customer satisfaction. We hope we have achieved this and have been able to remain competitive with our costings.

We are not the cheapest as we do not provide cheap products or service, and we are nowhere near the most expensive as we do not have the overheads or commissions that are paid by others.

We believe we offer value for money in comparison to others and ask you to judge us yourself.

Will the installers make a mess?2018-09-17T11:29:23+00:00

Our installers are respectful of your property and will lay thick dust sheets covering to the floors. They will tend to start with the upstairs windows and work down through you property; they clean and vacuum up the mess. When they have finished, they will take you on a tour of your products and advise you on how to maintain and use correctly.

What will I need to do before the installer arrive?2018-09-17T11:28:45+00:00

There is very little that you will need to do – all we ask is that there is easy access to the rooms in which we will be installing in. Also, it does assist us to remove your blinds or curtains and remove ornaments and pictures from the internal sills.

How long will it take to fit my new products?2018-09-17T11:28:17+00:00

Timescales vary depending on the products you are purchasing. Individual units can be installed in a day, whereas a conservatory can take up to 6 weeks to be completed. The best advice is to call a showroom and speak to someone to find out more accurate information.

How long will it take until the products are installed after I order?2018-09-17T11:27:45+00:00

Depending on the products you are ordering, the waiting list can vary Conservatories have a longer waiting list which can be between 8 to 14 weeks, whilst windows and doors are between 6-10 weeks. Time frames are seasonal with the Spring/Summer being more popular for conservatories.

What locks do you use?2018-09-17T11:27:13+00:00

We use a range of different locks depending on the product. All products are tested and have passed British Standards.

How can I be assured of the quality of your products?2018-09-17T11:26:40+00:00

We have looked to make quality our highest priority and our window and door system have been tested and passed:

  • British Standards Institute Kitemarks
  • British Board ofAgrément Certificates
  • Secured by Design
How do you install double glazing?2018-09-17T11:26:06+00:00

Realistic windows are installed professionally by one of our highly experienced installers. Windows, doors and conservatories are no different than other building materials and need a professional and keen eye for detail. Your products are only as good as the fitters who install them but equally they have to be measured correctly. Poorly measured windows cannot be installed correctly, and badly installed windows will reduce the life expectancy and energy efficiency capabilities of your frames.

What is condensation?2018-09-17T11:25:48+00:00

Condensation is the moisture caused by everyday living and occurs when warm moist air comes into contact with cooler air, or a cold surface, which is at a lower temperature. When moisture vapour forms, condensation is allowed to build up over a period of time and some properties can see this appearing on their windows.

If you have condensation forming on the inner pane of your windows, you will need to encourage ventilation; a trickle vent to the head of the frame can accomplish this, as can upgrading your windows to new energy efficient frames and glazing.

Condensation between the panes of glass means that the sealed unit has perished over time, the unit now has air between the 2 panes of glass and will only continue to deteriorate over time. The unit inhales more air and ultimately more moisture to form, the unit is not now working and needs to be replaced.

What is Low-E glass?2018-09-17T11:24:49+00:00

Low-emissive (Low-E) glass is window glass which has been treated with an invisible metal or metallic oxide coating, this creates a surface that reflects heat, while allowing light to pass through. Windows treated with Low-E coatings are proven to reduce energy consumption, decrease fading of fabrics, such as window treatments, and increase overall home comfort.

Do you provide secondary glazing?2018-09-17T11:24:01+00:00

We can provide aluminium secondary glazing for our clients, designed for listed buildings and homes in which you may wish to retain the original features.

What benefits will I gain having new PVCu windows?2018-09-17T11:23:29+00:00

Double glazing, especially A+ windows, will keep you much warmer and the PVCu profile is designed for little maintenance. You’ll still have to clean them and oil occasionally, but you will not have to paint them.

You will be more secure in your home with passed Secured by Design window systems, having products installed by professionals and fabricated to the highest standards. You will have windows which will be performing and looking good for years to come and fully guaranteed if something goes wrong.

How can I pay?2018-09-17T11:22:58+00:00

You can pay with a debit or credit card (2.5% handling fee), BACS transfer, cash or monthly with our home improvement loan arranged through Barclays; more information is available upon request.

When I go ahead, will I have to pay a deposit?2018-09-17T11:22:15+00:00

A deposit will be required for your home improvement and the remaining balance will be paid upon completed installation.

If I have someone around, how long will they take?2018-09-17T11:21:48+00:00

It will take as long as it takes for you – there is no rule on how long an appointment will take, it’s much more the case of how much information you require. Our consultants want to provide you with all of the information you need to make a decision and unlike most companies we will not be offering ridiculous discounts, calling managers or inventing money off schemes to get you to buy on the day.

We can provide you with a written quotation and hope you have at least 2 other quotations to compare, before you make a buying decision.  We are confident enough to know you’ll come back.

Do you offer an insurance backed guarantee?2018-09-17T11:21:12+00:00

Yes we can offer an insurance backed guarantee (IBG) with all orders. Our IBG is with the Glass and Glazing Federation Insurance (GGFI) who are owned by the Glass and Glazing Federation who also happen to own FENSA. It has been important to us that you know and have trust in a name that you recognise; there are many other lesser known, cheaper companies but we believe you cannot put a price on peace of mind.

With the installation of new windows and doors, you should be offered an insurance backed guarantee,. Regulations have been put in place to protect the general public from unscrupulous traders. Unfortunately, there are still many people not been given the correct advice and documentation.

What are the Building Regulations on windows?2018-09-17T11:20:42+00:00

Replacement windows and doors must comply with Building Regulations for replacement. Our consultant will be aware of the relevant specifications that need to be adhered to. These will include fire exits, child safety hinges, room ventilation and toughened safety glass. New build properties and extensions comply with new build building regulations. We are a FENSA registered company, meaning that you will receive the applicable certificates of Building Regulation compliance.

Do you make arched and round windows?2018-09-17T11:20:25+00:00

We can make arched and circular windows, we can even make combination windows and doors which are arched.

Can you do any type of bay windows?2018-09-17T11:19:29+00:00

Yes, we have a complete range of bay options – Box bay, Bow bay, Circular bay, Oriel and Plant on bays, you can be assured that our expertise will be at hand to guide you through the decision making process.

What is the life expectancy of my new windows?2018-09-17T11:18:54+00:00

Our windows are fabricated to exceptionally high standards meaning that they will last for many years. We offer a full 10 year guarantee on the window frames and a 20 year guarantee on the warm edge sealed unit range.

How much will my windows cost?2018-09-17T11:18:22+00:00

All of our windows are tailor made to your home; all windows are made to measure and are unique to your designs, and this can make two properties next door to one other work out to be completely different prices.

Still, unlike other companies who shy away from costs, we like to give people a guide system to work within. If you were to calculate £500.00 per window and £1000.00 per door, you will not be far adrift. Additional cost will be applied for extras of your choosing.

Do you offer self-cleaning glass?2018-09-17T11:17:46+00:00

We do offer self-cleaning glass but currently this will not give you an A+ rated window as this type of external pane glazing doesn’t comply with the present regulation. That is not to say you cannot have it, your windows will still be energy efficient compliant.

Will my new windows reduce noise?2018-09-17T11:17:15+00:00

This will depend on the type of windows that are being removed; our windows have a 28mm sealed unit as standard with 4mm exterior glass panes. You could also opt for triple glazing as high performance glazing provides greater interior acoustic comfort and noise reduction. Contact us for more details.

How much money will I save having new windows installed?2018-09-17T11:16:39+00:00

This depends largely on the type of windows you are having replaced in the property. The majority of the installations we carry out are replacing aluminium and uPVC windows. The typical amount of monies you can save based on statistic produced by the Glass and Glazing Federation (GGF) are:

Typical house* upgrading from single glazed timber windows with electric heating to A rated
£325.26 Annual Saving

Typical house* upgrading from pre 2002 double glazed PVC-U windows to A rated
£156.69 Annual Saving

*A typical detached house has 23.7m2 of windows. Source Glass and Glazing Federation.

We have had more positive feedback from feeling warmer with new windows and doors; eliminating cold drafts has a big part to play in this.

What is a U value?2018-09-17T11:15:36+00:00

A U value is a measurement of heat loss in a building component such as a wall, floor, roof or window. It can also be referred to as an ‘overall heat transfer co-efficient’ and measures how well parts of a building transfer heat. The higher the U value the worse the thermal performance of the building covering. A lower U value indicates a higher level of insulation.

What is an A+ Energy Rating?2018-09-17T11:15:02+00:00

All relevant products must now have an EU Energy Label clearly displayed when offered for sale or rent. Properties therefore need to have an EPC (Energy Performance Certificate) to be sold or rented. The energy efficiency of a property is based on class bandings from A through to G, A being the most efficient. The rating of your windows will go towards the overall total band that your property achieves.

Can you match my existing style of window?2018-09-17T11:13:13+00:00

We cannot promise our windows will exactly match your existing windows but our PVCu profiles and colours will blend in with any home. We have an extensive range of wood grain foil finishes and can colour match any of the RAL range in PVCu and aluminium. Plus, we have 3 individual frame finishes with Chamfered, Sculptured and Flush Frame sash.
