Is Blackmourne Contracts Ltd FENSA or Certass registered?
This directory does not confirm registration. Window and door installers self-certify their work against Building Regulations through a Competent Person Scheme — mainly FENSA or Certass — so check the company name or postcode (BT34 2JG) directly on the FENSA or Certass website before booking, and ask to see the certificate number.
How much does window replacement cost in Newry?
A single uPVC window in Newry typically runs £300 to £600 supplied and fitted; a full house of 8 to 10 windows is often £3,000 to £8,000 depending on style (casement, bay, sash-look) and glazing spec. Get two or three written, itemised quotes before agreeing to work.
Can I see reviews for Blackmourne Contracts Ltd?
Not here. This is a register-based directory, not a review site. Look at independent review platforms, ask the installer for recent local references, and confirm FENSA or Certass registration before any work starts.
Is new double glazing covered by a warranty?
uPVC frames typically carry a 10 year manufacturer or insurance-backed guarantee, and sealed glazed units are usually guaranteed separately for 5 to 10 years against misting. Register the guarantee after installation and keep the FENSA or Certass certificate — a buyer's solicitor will ask for it if you sell the property.
How many window and glazing companies are there in Belfast?
This directory holds 524 active window and glazing businesses across 79 towns in Belfast, all from the Companies House register. Newry accounts for 81, among the county's busiest. About 38% of Belfast's registered window and glazing firms were incorporated in the last three years, so weigh incorporation date and FENSA/Certass registration, not just company age.
