Our story
A family business built on honest work
P Black & Son was founded on the values of hard work, quality craftsmanship and honest customer service. As a family business, we've continued to build on those foundations, growing and evolving while staying true to the values that started it all.
Who we help
Homeowners. Most of our customers are households replacing tired windows and doors, extending, renovating or building their own home.
Experience
15 years of supplying and fitting, with a team of three fitters and two subcontractors.
Where we work
From our base in Coleraine we work across Northern Ireland and occasionally further afield.
What we specialise in
Bespoke aluminium and steel. We supply and fit Origin aluminium, our best seller, and RK Steel windows and doors for inside and out. We also supply Palladio and Bel'M. Our bespoke aluminium work covers bi-fold, sliding, French and internal doors, windows and glazed gables. Our sister business, Coleraine Glass, supplies and replaces glass staircases, double glazing units, mirrors and splashbacks.
It's not just about supplying windows, doors and glass. It's about building lasting relationships, earning our customers' trust and taking pride in every project we undertake.
Mission and standards
How we work on every job
Quality standards
Every product is made to the measurements taken at our survey, and every frame is fixed, packed, sealed and tested before handover. We tidy up as we go.
Service philosophy
Straight advice. We supply products from several manufacturers, so we recommend what suits your home, not what we need to sell. The team that surveys your home fits it.
