DIY Double Glazing, Going Down The DIY Route

If you’re short on budget, then when not try DIY double glazing.

It is possible to fit double glazing yourself and taking this course of action will enable you to save a considerable amount of money. However, unless you are proficient, highly competent and have all the right tools, it could be a disastrous and expensive decision to install DIY double glazing.

The first thing you need to do is apply for Building Regulations approval from your local authority. Once this is granted you need to find a specialist supplier who can carry out a site survey. The cost should be reasonable and could prove to be a very sound investment.

The surveyor will advise you on what is appropriate for your property and your needs, give you guidance on openings and ventilation and outline any requirements for safety glass, fixed open trickle ventilation for gas appliances and fire escapes.

Equally importantly, all measurements and specifications will be the supplier’s responsibility. All the extras – trims, packers and sealants, etc. – to do the job properly can be specified and included in the price. It is much cheaper and more efficient to get these from the supplier, who buys in at trade prices.

Things to consider when choosing a supplier:

  • Don’t buy solely on price
  • Secure a 10-year product guarantee
  • Check whether the supplier will deliver to, and offload at your home address
  • Ensure there is a sound after-sales and advisory service
  • Enquire whether telephone and on-site support is available if you come up against problems

Other points to consider when installing DIY double glazing

  • Bow or bay windows are tricky and only for the extremely proficient
  • Start with a confidence-boosting small downstairs window
  • Fitting PVCu is completely different to fitting wooden frames
  • Never rest glass sealed units on edge on concrete, as they are very likely to ‘shell’ and then crack as you handle or fit them
  • Always secure your ladder firmly or, better still, get someone to hold it for you
  • Think twice before tackling this task!
