Safe and Secure

My experience of the service I received from the Concierge Team was always good. They were friendly and polite, conscientious, discreet when required, and I always felt that they listened and understood my needs well and did their very best to assist whatever the circumstances. I appreciated that there wasn’t always a quick fix for everything but if they could respond promptly they did, escalating other issues raised or reported to the relevant contacts e.g. within the Mainstay team, utilities etc.

I always felt safe and secure in my 13+ years living here, which was important to me, especially in the latter years when I lived by myself. Having a dedicated Concierge Team meant a lot to me, for example, I knew that if I didn’t turn up for work one morning and hadn’t responded to attempts made to get hold of me, that my manager could telephone KEW and whoever was on duty would attempt to check that I was okay, being able to telephone down to the Team at night if there was anything untoward happening outside, holding a spare key for me – a myriad of things that made me feel comfortable. I know also from feedback from my guests that they were impressed by the staff.

Justyna Sedziwa deserves a special mention. She’s good at her job and has built up a good solid team around her.

Last but not least, I have to make mention of the Maintenance Technicians, for the work they did to keep everywhere up to standard and for the support freely given in the times I needed some help– thankfully there were only a few!

Amazing Job

I am a lease holder at timber wharf and have been for 8 years 9 months.

I just wanted to feedback personally on the role Mainstay have had and particularly Kate McGill and Glynn Poole with regards to the roofing works here.

As you can imagine this has been frustrating and difficult time for many lease holders. Mainstay, Kate in particular have done an amazing job in juggling so many stakeholders, issues, opinions and ultimately works well outside the usual remit for a management company.

You have proven to be the biggest ally of the timber wharf residents and your staff have gone above and beyond to accommodate the various requirements of residents, contractors and all involved. Taking time out of weekends and evenings, always being approachable and providing complete transparency throughout the process.

I have personally felt that mainstay get much less credit than they are actually due and would like to take this opportunity to thank you and all involved, I feel the resolution we have reached is amazing and a testament to the tenacity and hard work of Kate and your team.

Positive impact

Mainstay's impact has been very positive. The response to questions and issues from our residents has been timely in the main and Martin has started to tackle some of the more difficult problems that we face.

He has been excellent in pulling together the work schedules for both maintenance and our longer term development plans. He has been responsive to my requests and has followed matters up promptly. He provides regular well written updates and is generally available when I need to speak to him.

My board are very pleased with Martin and I have already asked that he remain responsible for our development.

Helpful and Friendly

I would like to take a few moments to compliment all the hard working and friendly staff at the Orion Building in Birmingham. Myself and my family have been owner/residents for the last 8 years or more, and have been particularly impressed with the current building manager .

He is always friendly and approachable despite a significant workload and has overseen numerous improvement schemes including the lighting sensors in car parks. He is always positive and motivated , and strives for excellent relations with residents and continuous improvement of the development. His maintenance team are also excellent and follow his example, and the whole concierge team are helpful and friendly, and enhance the experience of living in the Building!

Thank you

Friendly and Approachable

I moved into The Unity Building when it was still being developed so I am an original leaseholder; Mainstay has managed the building since day one and to be still managing the building 9 years on shows what a good job Mainstay here. The concierge are all friendly and approachable and in some ways have become an extension of my family, I speak to most of the team on a daily basis.

The communal areas are immaculate, maintenance issues are always addressed and I know my investment is well looked after by Mainstay. This is a huge building that takes a great deal of upkeep, I accept it is not going to be cheap living here but at the same time I know my service charge is being well spent and explanations about expenditure is always clearly communicated.

Kate Magill is extremely hard working and has done a great deal to get the developer back to site to address extensive issues with the cladding, my apartment has suffered water ingress since day one but I have accepted that this problem will be addressed because Kate has always communicated clearly and accurately about the progress of the works. At times I worried we the leaseholders would end up footing the bill but we now have mast climbers up all around the building and that reassures me the works are now well underway.

Kate is friendly and approachable she is extremely well regarded by all the leaseholders, I never e-mail Kate because I know she is on site weekly so I just pop down and see her, she always makes time to speak to me.

I actually moved out of Unity Building 12 months ago because I wanted to live out of the City in a house, I lasted four months before returning because I missed the building and that is down to Mainstay and their staff.
