Replacement vs Repair

You’re not happy with your existing windows and doors. So what do you do?
Repair or replace?

Here at Core Sash Windows, we have tried our very best to summarise what is included in each service so that you can make your own informed decision.

Common Issues

Double Glazing

It is fairly common knowledge that double glazing can retain heat and block sound more effectively than single glazing. This will keep you warmer in the winter (but also cooler in the summer, thanks to our Low E glass), save you money on energy bills, have less impact on the environment, and make your home much quieter. If you currently have single glazing, and do not live in a Listed Building, we strongly suggest that you opt for the replacement route. We feel that the practical benefits of double glazing mean that you should never intentionally stay with single glazing, unless the decision is out of your control (such as in a Listed Building).

We are also aware that many of you will live in Conservation Areas, and may be concerned that double glazing would not be a viable option for you, either. However, this assumption is not true. Much of the hostility towards double glazing from Conservation Officers is due to the non-traditional style and profile of common double glazing, and not a result of the act of replacement in itself. Providing you make every effort to replicate the existing style and profile, Conservation Officers can actually be very accepting of double glazed replacements.

Existing Material

So let’s say that you don’t live in a Listed Building, or a Conservation Area, and you even already have double glazing; why could you possibly need a replacement? We often have customers call up who have perfectly functional double glazing, but they are still looking for a replacement service. The reason can be explained in only 4 letters: uPVC. We have previously released an entire blog post on the negatives of uPVC, but to summarise; uPVC is toxic, impossible to repair, and is not maintenance-free. Some customers also want to restore their properties to their traditional appearance, despite having no legal requirement to do so. It is for these customers that we recommend our replacement service.

Existing Style

Pretty self-explanatory; you want to swap from sash to casement, or from casement to tilt and turn. Comparable to changing your Ford Fiesta in for a BMW M3; they’re both fundamentally the same thing (cars), but you have made this replacement out of personal preference more-so than practical requirement. In this case, repair isn’t an option as there isn’t an issue to repair.

Draughts

Due to the design of a traditional sash, there are functional gaps around the edge of the sashes which allow them to move freely (and therefore open). Unfortunately, these gaps can allow draughts in, despite the double glazing being perfectly functional and acceptable. Unlike Core Sash Windows, not all double glazing installers include draught-stripping as standard with their replacement products, and so it is perfectly possible that your new double glazed replacements may still be experiencing unwanted draughts. We will happily install Aquatex Weather Seal stripping in your existing sashes, thereby preventing these draughts, if you are otherwise happy with you existing windows, or can offer full replacement if draughts are just one of many more issues that you are experiencing.

Minor Imperfections

We understand that nothing lasts forever, and therefore it is perfectly possible that your windows and doors may simply need a little bit of love and affection over the years. Perhaps your latest DIY attempt to re-paint your sashes has resulted in them sticking? Maybe the lead weights in your sash box have become tangled? In these cases, we would usually recommend our repair services. Whilst we do not have a comprehensive list of the minor imperfections that we can deal with, there are several issues that can be adequately resolved through the works included in our Draught Proofing service. (As an example, we have to remove and re-fit the sashes when draught-proofing, and in doing so, we would resolve any sticking or entanglement problems). If, for any reason, our repair services are unable to fix your specific issue, we can always offer a full replacement service instead.

So. That’s a summary of the most common issues, and our typical solutions to deal with them. But what exactly is included in our services, and what’s the full story behind them?

Please note that individual aspects unique to a particular service are highlighted in red, so that you can identify the key differences at a glance.
