Sealing external windows
The quote I received for the work was fair and reasonable. The workmen turned up on time and did an excellent job of sealing my windows.
I would have no hesitation in recommending the Company for sealant work.
Would highly recommend this company
Would highly recommend this company. Our outside windows and cladding needed to be resealed and was done very well. Cleaned up as they went along. It's now looking good - job well done!!! 👍
Brilliant job throughout
Absolutely the best company we've worked with in a full house renovation. John was amazing from start to finish. Great communication throughout, turned up in time, did an excellent job sealing our kitchen and bathroom - he even had every colour under the sun available to correctly match different units. John was kind and personable, and went out of his way to fix another small area we had overlooked. Highly recommended!
DO NOT USE THIS COMPANY !!!
DO NOT USE THIS COMPANY !!!
After reading the reviews I felt reassured to use John Cairney but they must be false reviews as my experience was awful.
Turned up 1 hour late for our appointment without any courtesy call. Poor attitude when he walked in my house but I tried to look past this as I needed my bath resealed. After job was done I told pointed out areas of his work that I wasn’t happy with and instead of fixing it he was very rude and abrupt so I just paid him to get him out my house.
Never…again !!!!

What a brilliant service
What a brilliant service. John came and quoted and booked me in. Turned up on time, left a clean job. I have my bathroom resealed and windows.
My bathroom looks like it’s new. Absolutely delighted
Reliable service
High Quality, friendly and professional service
John and his team were so accommodating with my request, at short notice, to re-do the sealant in both the bathroom and kitchen. Him and his team completed the work to a very high standard. Thank you! Would recommend G1 Sealant to everyone.

Amazing job carried out
John has been fantastic to deal with, from initial contact to having job done. Couldn’t fault him at all. Work carried out to a very high standard. Looking forward to having him come back to do more in future. Would have absolutely no hesitation in recommending him

Fantastic Company
John Cairney of this company is everything you could wish for in providing a first class service. He transformed our badly soiled mouldy shower unit into a sparkling white finish. The job entailed removing dirty worn anti slip sticky pads, cleaning up the residual mess then applying sealant to the shower base. The result is spectacular.
John is also a good communicator in contacting me promptly, giving a reasonable price & arranging a day to provide the service. How refreshing it is to find a company like this & I highly recommend him. My thanks to John & his associate.

Window mastic replacement
After contacting John about draughts coming in from multiple windows, he was able to identify breaks in the existing mastic sealant. Once identified, these were actually easy to spot.
We booked a suitable date and had the sealant replaced around all top floor windows on the house and most of the downstairs. John even replaced the sealant around a door free of charge!
He arrived when he said he would, tidied up afterwards and now we will have a leak free and draught free home in time for the cooler months coming.
Overall, we had a great experience and wouldn't hesitate to recommend G1 sealant.

Quick response to help my Mother in law.
John helped seal my Mother-in-laws garage after I was let down by a previous contractor.
He was quick to respond, helpful and arrived as planned and let my WiL know in advance.
Great service and happy to recommend.

Replacement Sealant
I needed the sealant in my shower removed and replaced. John was recommended and he arrived on the date agreed, bang on time. His work is first rate and he left the job spotlessly clean. I am more than delighted with the results. I would highly recommend John and will definitely use him again.

Exceeded expectations
I booked John in for the next availability he had a couple weeks later to reseal my shower unit. I didn't have high expectations of him showing simply as been let down so many times with other workies. John was very prompt and arrived when he said he would and it made me nervous as I left my husband at home that day as I was at work and again didn't have high hopes for a great job 😂. When I got home I was so happy that the work that was done, it exceeded my expectations and the attention to detail...wow - everything was perfect!

Bathroom Resealed
I called upon G1 Sealant to reseal my bathroom due to a very bad experience I had with a previous sealant company who not only did a poor job but had also damaged my shower tray too. John came out & done a fantastic job. I was delighted with the result’s. He is very meticulous on what he does. I would 100% recommend G1 Sealant to friends & family & I’ll be getting John back again soon to do my kitchen too.
