Heath Windows and Doors Cardiff

 After 10 years of excellence in the window and door installation business, we know a thing or two. Mostly, we know that people want peace of mind. You want to know that the products you buy will do the job well and stand the test of time. We are a family-owned and operated business and operate from a position of pride in the service and products we provide and care for our customers.

What to Expect from Your Consultation.

Our staff are highly experienced and fully trained.  They are there to help you make an informed choice. Whether you need more information about a product, have a question or need help choosing the right window or door for your home, we will take the time to understand your needs and provide sound advice.

Miall Hardwick is the Director of Heath Windows and Doors Ltd and is very much hands-on. At some point during your journey with us, he is likely to be involved.

Whoever, you see, you will find that everyone is passionate about the business. We are straight talkers who deliver what we promise. We never pressure you into purchasing something you don’t need. Buying home improvements should be exciting. We make every effort to make it a pleasurable experience from start to finish.


Fair and transparent PricingNo Inflated Prices to show False Discounts.

It can be a problem for genuine businesses to compete with the companies who double their prices to advertise 50% discounts. When we don't offer these discounts, customers can think it means that we are expensive. This is a misconception born out of the discount culture that is prevalent in the home improvement industry. What do you want? A price that starts at £10,000 and is reduced to £5,000 after a couple of hours of haggling or someone who carries a genuine price list and tells you straight away that the price is £5,000?

Buying home improvements is an intensely psychological process.

The fear of missing out means that customers often make buying decisions based on fear rather than taking time to make the right decision. The difficulty for us is that we want to be straight and open with you. We don't want to spend our time with you explaining the tactics of other companies or telling you about the stories we here. It makes us seem unprofessional and changes the dynamic of the appointment to combative when we just want to keep it all nice and friendly.

We want to know that you make the right decision whether you buy from us or not. It really upsets us to hear some of the stories. To this end, before buying from us or anyone else, we invite you to read some of the articles from the Home Improvement Sales Association. These will tell you exactly how these discounts are sold to you.

In particular, read these articles:The Scrappage Scheme' and Other Myths.  False Discounts in the Home Improvement Industry.

When you visit our showroom, or we visit you, we will measure, advise and either give you a quote there and then or send it to you. It will be the best price we can give. You won't have to haggle or wonder whether you should have pushed for more. If you read through our feedback on Google, you will see that this approach is mentioned in the comments.

We Have the Experience to Do the Job Right.

The double glazing business is inconsistent throughout the year so most companies use self-employed contractors so that they don't have salary overheads during quiet times. This can lead to inconsistent standards. This isn't good enough for us. We want to control the standards on every installation. For this reason, we fully employ our installers. This also means that our installers can take time out for training because they don't lose income while they do so. 

Our team tackles even the most difficult installations with confidence. Our employees are Allchecked installers who are qualified for the most complex window and door installations.
