Your floor does not have to be freezing cold and draughty during the icy Canberra Winter.  No matter the age of your home, there is a high-performance retrofit insulation solution available.

Spray foam insulation locks in heat and seals out draughts.

No Canberra home needs to have uncomfortable floors… ever.

Spray foam insulation (SPF) is a spray-applied insulation that is widely used to insulate buildings and seal cracks and gaps, making the building more energy efficient and comfortable.

SPF insulation is known to resist heat transfer extremely well and it offers a highly effective solution in reducing unwanted air infiltration through cracks, seams and joints.

Fortunately there is a simple solution to your floor insulation woes…

Very prompt and polite. Always called before coming. Good quote. The guys installing did a great job plus insulated a bulkhead that wasn’t in the quote. Further put in fan seals so they had to get back on the cavity. Amazing service. Plus the job looks perfectly complete.

Rob Narel, Duffy, ACT

I’m very impressed with the results – my house is 10-12 degrees cooler since I had my roof and walls insulated In September. Today with temperatures outside around 40 degrees the inside thermometer is showing 28 and I haven’t turned in the aircon! Staff at the office and installation team were a pleasure to deal with – very professional and efficient.

Lilian Prdjan, McKellar, ACT

Very responsible attitude, giving me a reminder of booking in time. Boys on site are hard working!

Ann Yan, Red Hill, ACT

The team at Alexander Watson were exceptional, very professional from first quote to final install. They did under floor spray foam insulation, it’s fantastic.

Liam Hart, Scullin, ACT

The boys came out during a Canberra arctic blast and sprayed our van. Highly recommend. Great customer service and the product speaks for itself.

Martina Johnson, Murrumbateman, NSW

Great job, efficient staff, pleasant, competent and a great price for foam insulation under my deck. A big difference to the room. Thanks Alexander Watson! JT

Jonathan Taylor, Melba, ACT

I just had wall and ceiling insulation, as well as removal and clean up of old insulation completed from the team at Alexander Watson. The office staff were so professional and responsive with their communication throughout. Their prices were competitive and the team who installed were really friendly and efficient. We’ve just had our first series of cold days/nights in Canberra and I can feel the difference already. Thanks guys! Highly recommend you.

Jen Margules, Weston, ACT

Had the walls in an old 1897 house done by these guys last week. best money I have spent. Temp has gone up in the affected rooms by at least 8° and I now have even temperatures through the whole house. Even had to turn the heater down, will make a huge difference on energy costs. The installers were professional and knowledgeable and the whole job went like clockwork. Job well done on all levels. thank you.

Julie Hays, Queanbeyan, NSW

Hard workers. Cleanliness was paramount. Under estimated the work to be done but stayed after hours to make sure the job was completed. House so warm now.

Roy Volmari, Hawker, ACT

We have been extremely impressed with the service we received from Alexander Watson.
The whole team have been super friendly and professional. The work carried out at our home was completed on time without any mess whatsoever, they all did a fantastic job and we cannot believe the difference it has made in the temperature of our house, highly recommend Alexander Watson!

Suzie Walden, Kaleen, ACT

Really great service, care and attention to detail. Fantastic after-care as well. Couldn’t recommend highly enough, especially if you’re doing a retrofit!

Rachael Thoms, Casey, ACT

Excellent service provided by cooperative and friendly business. I would have no hesitation recommending them.

Fiona Engeler, Ngunnawal, ACT

We would highly recommend Alexander Watson for home insulation. They have just retrofitted under floor, wall and ceiling insulation to our 1960’s home And have already noticed our central heating reduce the amount of time it kicks in. Their service before and after has been sterling and couldn’t ask for anything more. They may be a bit pricier then some others but you really get what you pay for.

Kate Lyall, Garran, ACT

Brilliant service – prompt and efficient from the girls on the phone to the chaps who did our job. Appreciate everyone’s efforts (travel etc) excellent service!

Lynne Arnold, Cudmirrah, NSW

Great service and already feeling the difference.
The guys who came out were great and explained everything perfectly.
Definitely will be recommending.

Alan Horner, Higgins, ACT

I cannot recommend Alexander Watson Insulation any higher. We were really well looked after in terms of competitive pricing and the whole team were so lovely to work with. We had our insulation installed this week and the difference is already outstanding. We have had our heater on every evening since moving into our new home and since having the insulation in, it is the first time we didn’t have to turn it on.

Ashley Thompson, Macgregor, ACT

Already noticed the difference with a few freezing nights. The staff were professional, informed us what they were doing. Thanks!

Liam Hart, Scullin, ACT

Why spray foam instead of installing batts under your floorboards?

There are a number of reasons why, one of the most important being that floor insulation should not be measured in “R Value” alone.

But wait… There’s more…

No More Draughts

Insulation and draught sealing in one.

CREATE AN AIRTIGHT SEAL...

Heat rises, so why worry about insulating the floor? Yes it is true, heat rises, and will move to the top of your house, however the convection will continue to bring the cold air from outside up through the floorboards and continue to cool the house down. What our high-performance spray foam insulation does is create an airtight seal.

An End To Squeaky Floors

Spray Foam insulation eliminates all the squeaks.

NO MORE NOISY FLOORBOARDS...

High-performance spray foam insulation under your floors creates a perfect airtight seal under your home but one of the other major benefits to installing this product is that you will forever eliminate noisy or squeaky floorboards. Prepare yourself for comfortable warm floorboards in the winter months that are just as quite to walk on.

The Healthy Choice

An airtight seal means no irritants coming through the floorboards.

NO MORE DUST...

Having gaps in your floorboards means dust and other irritants can easily blow into your home from the gap under the floor aggravating allergies and causing discomfort. By installing high-performance spray foam insulation not are you only creating warm, quite floorboards but the airtight seal means you lock out these unwanted irritants.

No Sagging Batts

Spray foam insulation adheres directly to the underside of the floor.

SPRAY FOAM STICKS AND STAYS...

If you have batts installed under your floorboards they will more than likely begin sagging over time reducing the insulation and still leaving gaps under the floor. Unlike batts that will sag, high-performance spray foam insulation adheres directly to the underside of the floorboards and will create a airtight seal under your home for life.
