We had every window replaced in our house. Paul and his team delivered a top quality product which has enhanced our house and has met all our expectations with insulation and noise reduction. The professionalism from beginning to end was second to none. The product was installed ahead of schedule and we are so glad we supported local business and were rewarded accordingly. Highly recommend Heatseal Bunbury.

From our initial enquiry right through to the installation of our double glazed windows, the advice and service we've received from Paul and his team has been fantastic.
Our house is by the beach and is fully exposed to the harshest elements, so extra consideration has been given to the safety rating of the glass and frames. The windows are of the highest quality, with a very impressive locking system, and they have been fitted to perfection.
We have no hesitation in recommending Heatseal for quality windows and doors. Their product and their service is top rate.

We had 3 double glazed windows and front door installed yesterday by Heatseal and we are already blown away with the amount of traffic noise they have blocked, plus how attractive and contemporary they look. The entire process, from meeting the charming and knowledgeable Paul, through to his team of expert tradesmen installing the windows and door has been smooth sailing. It was clear from the beginning we were dealing with a consummate professional company. I wish I could give them 10 stars and I would happily recommend them to anybody wanting to upgrade their home.

Had sliding doors fitted by Paul and his team. Gary was very helpful answering my many questions when I arrived unannounced at the factory. The team did an outstanding job, fitting the sliding doors with the minimum of fuss, clean and tidy. We have received many compliments on how good our doors and windows look. I would not hesitate to recommend them for excellent quality upvc double glazing sliding doors and windows. Very happy! 10/10

We recently had Heatseal double glazed windows and doors installed. They save us a fortune in heating and cooling costs, keep out road and other neighbourhood noises, and look great. The whole process from quote to installation was a breeze and the boys did a brilliant job - they even clean up after themselves! - and the end product is excellent quality. I regularly recommend Heatseal and will continue to do so.

The guys from Heatseal did an amazing job to replace our old west facing windows and a door. The job was massive undertaking and was completed in a day with the guys cleaning up as they went along. By the time they had finished, we had great new windows and everything was immaculately clean. We added a tint to our windows and it looks terrific. I can highly recommend Heatseal, we are planning on getting more windows replaced and we are going to call them back again.

Can't praise the Heatseal enough. Andy was our the first point of contact, he was very professional, honest and not pushy. The installers, Steve and Jackson, arrived at 7am as arranged had a coffee then worked non stop until the job was done. No mess, hoovered inside swept up outside and left.
If anyone is looking at double glazing I would recommend Heatseal as your first port of call.
The windows lived up to our expectations, just like the UK.

WOW! I would like to take the opportunity to thank all the team at Heatseal Double Glazing. The level of service and communication throughout the whole process right from measuring, quoting and fitting our new double glazed windows and doors throughout our home have been fantastic.
We have had bad experiences with tradespeople over the years but I can truly say Heatseal's workmanship and service is exceptional.
Heatseal's visited our home at a time to suit our busy working schedule. He took the time to explain all the fine details ensuring we had the correct style, colour and designed windows
