The Cabinet agreed recommendations to appoint Mears Group at their meeting on 27 November.
Mears will be managing responsive repairs, planned maintenance and empty dwellings for Crawley Homes properties from 1 April this year.
The contract, which is valued at £167 million over 10 years will split the town into two areas, with Mears delivering maintenance in one area and Wates in the other.
Existing staff will be moved over the new contractors, ensuring no disruption to council tenants and the same familiar faces at appointments.
The chosen contractors came top in both quality and price, scoring highly for their approach to the environment and their commitment to the community.
Cabinet member for Housing, Councillor Ian Irvine said:
“This is great news for our council tenants, who will continue to receive top quality service. Here at the council we have a thorough process to ensure we get the best possible deal for both the organisation and our residents.”
Colin Middlemas, Chief Operating Office for Mears said:
I am very pleased we will continue to build on our relationship with the council. We place social value at the heart of our business and we look forward to working with them to develop shared objectives as to how we can contribute back into the community.
"Mears is not just a contractor but a local employer and our operatives are members of the community in which we will be working."
