What happens if there’s a problem with my new windows and doors?

• Firstly, please check your windows and/or doors before you remove any existing ones, to make sure everything is as you ordered it and that the specification is correct. It may take a few minutes, but once you remove any old frames you’re past the point of no return.

• Remember to check that everything opens and works properly, that you’re happy with the standard of the sealed glass units and that there are no imperfections in the glass – it can help to hold items up to the light . We will have already fully checked them before they leave our factory, so unless something has happened in transit they should be perfect.

• Make sure you read the Installation Instructions in full and make sure that you have all the necessary tools and fixings to complete the job.

• If you think you have a problem, send an email to our Customer Services department including details of your invoice number and the details of your query.

• Our Customer Services department may need to re-contact you if they need more details or questions to fully understand your query.

• If a genuine problem is established, Lycawindows expert team will pick up the item/s and bring them back in to
our factory for inspection, where they will be repaired or replaced, as necessary.

• If we aren’t able to find any problem we’ll organise to drop the products back out to you. Unfortunately, there will be a charge for the collection and re-delivery in the event that no problem isfound.

• As we make all of our windows and/or doors to measure, we aren’t in a position to just send a replacement out without establishing there is a genuine problem.

• We manufacture all our goods to a commercial standard and check against this standard when products are sent out and if they are returned to us.

• So in summary, we check them before we deliver them to you , you check them before you fit them and if there’s a problem we’ll bring them back in to inspect and replace if necessary. Simple!


A totally flawless piece of glass is very rare. If you look enough at any piece of glass, you will almost certainly find a minor blemish. The question that has to be answered is, is the flaw or mark of such a nature that it spoils the appearance of the window. In an attempt to help resolve what can be a contentious issue, the Glass and Glazing Federation has
devised the following test to enable both customer and glazing companies to examine glass against
objective standard.


Stand in the room no less than 2 metres away from the IGU and look directly through them.

• For toughened, laminated or coated glasses, stand no less than 3 metres away.

• Do so in natural daylight, but not directly towards the sun and with no visible moisture on the surface of the glass.

• Where it is not possible to stand at the right distance then stand as far away as you can from the IGU.

• Exclude 50mm wide band around the edge of the glass from the check.

• Glass must be viewed at 90 degrees to the window.


Flat transparent glass, including laminated, toughened (tempered) or coated glass (low ‘E’) is acceptable if the following are neither obtrusive nor bunched:

• Bubbles or blisters

• Fine scratches not more than 25mm long

• Minute particles The obtrusiveness of blemishes is judged by looking through the glass, not at it, under natural light. It must be understood that the glass used in double glazing is a processed glass, and so as a consequence, blemishes are to be expected. Insulating glass units with optical defects such as smears, fingerprints or other dirt on the cavity faces of the glass, or extraneous material in the cavity are unacceptable, except in some cases where small particles of desiccant can be seen.


Toughened glass may show visual distortions which are accentuated by reflections in double glazing. Such surface colourations and patterns do not indicate a change in physical performance. Low emissivity coating may produce transient visual effects.

In some lighting conditions the coating may look like a transparent film or produce a haze, ie a cloudy look to the surface. When light coloured objects such as net curtains are placed close to the glazing they may look slightly darker.

We only sell high quality uPVC Energy Saving Windows

Why buy energy rated windows?
We only sell fully tested and certified energy rated windows that we produce. The Window Energy Rating System, based on a scale of A to G, aims to distinguish which windows are the most energy efficient. Generally, certified energy efficient windows have a number of key benefits:

• Increased insulation improves heat retention, helping keep your property warm

• Greater heat retention will help reduce your energy consumption and your energy costs

Are higher rated windows worth the money?
In a perfect world, all homes & buildings would be built of the most energy efficient materials, in order to conserve the worlds resources and to have the lowest environmental impact. Unfortunately, unless you live or work in a very recently built property this is very unlikely to be the case.

The development, use and cost of ‘A’ rated thermally efficient glass, for most properties, is unlikely to make any significant impact on energy reduction, compared to the ‘C’ rated glass we sell. It generally will also cost you between 10-20% more. Significant additional energy efficiency in a property is only really achievable if you are able to improve the insulation of your walls, roof and floors, which is where most of the heat dissipates through.

So we’d advise you to save money on the glass that you buy and spend it where you would get a greater return on your investment.
