Paul and his team recently installed a lift and glide door and windows for our whole house. They are so beautiful and have made an amazing difference to the look of our home. The lift and glide door is absolutely stunning! They were so professional right from the first meeting, to scheduling and through to installation. We were very impressed and we highly recommend Paul and the Heatseal Double Glazing team.

If you're looking for an insanely solid windows and frames to sound proof or insulate your house then look no further. These guys are absolutely amazing to say the least. Their products are also well and truly above and beyond what you'd expect and the entire process has been nothing but amazing. Can't thank the team enough for all their work.

As far as my use case goes, I have quite a large hifi and seperate cinema system which can get insanely loud so I needed some serious glass to help keep the noise contained and this goes above what I was expecting. Anyone who's serious about their cinema needs to give these guys a call.

We had Heatseal install windows and doors at our previous home and we knew that the double glazing worked and was very efficient. We have found in our new home that the early morning temperature in the lounge area has been reduced by a good 5 - 10 degrees due to the new windows. Nathan, who did the job, was very efficient, a clean worker, friendly and eagerly helped us move furniture. 10/10 for the whole team.

10/10 - would recommend HeatSeal to all family and friends - and have done so.

Price - affordable and competitive quote. HeatSeal was the only company open to completing smaller orders (not an entire new house build).

Innovative options - HeatSeal has the option of uPVC frames and double glazing.

Customer Service - Professional and friendly customer service by entire team.

Office staff and invoicing - simple and easy invoicing with instalments and quick and friendly response times by admin team.

Quoting staff - Professional and friendly. Explained works options in clear and simple terms to easily understand.

Trades - Set timeframes and met expectations. Clear communication throughout. Window was broken and boarded up - HeatSeal went above and beyond to complete works as soon as possible because of this. Final result - exceeded expectations, looks great!

We’ve had several jobs undertaken by Heatseal, from replacement of several of our window frames and a door cut into a wall to access a new outdoor patio area.

Regarding the door, we went in wanting a French door but were unable to go with this due to space/engineering challenges. Paul went through our options to get something that was suitable for our needs and he has a sixth sense to provide a product that went above and beyond what I had imagined we’d end up with.

With our windows, we had our hearts set on the European style tilt and turn frames, something that’s a rarity in Australia and Heatseal were one of the few installers that offer this option. Not the cheapest way to go, but the quality and functionality was well worth it.

I can’t recommend highly enough the level of quality and service from Heatseal.

After considering upgrading our older windows in the kids bedrooms to double glazed for years, experiencing the Bunbury tornado in 2024 quickly made that decision immediate. And what a shame we hadn't done it 10 years ago... the noise reduction, heat insulation is truly remarkable and the kids are now back sleeping through the night in their own beds. The fitting to the older frames was seamless, look great and all round service has been excellent. A real game changer for us, thanks Heatseal Bunbury
