Welcome to Sparrow Locksmiths, your trusted provider of UPVC & Double Glazing services in Northampton and surrounding areas. We specialise in ensuring the security and efficiency of your residential or commercial property through our expert UPVC and double-glazing solutions.

UPVC doors and windows are gradually replacing traditional timber windows. You can find them installed not only in office buildings, block of flats and business apartments, but also in cottages and private houses. This happens because UPVC has a number of advantages over wooden materials: it is customizable (can be of any size and shape), provides high level of security (in combination with modern locks and locking mechanisms), it is energy efficient, provides good sound insulation, durability and low maintenance.

But like any other material, UPVC locks and mechanisms tend to wear out with time. Doors and windows require regular maintenance or sometimes one may need to replace the locking system with a new one.

Most typical problems for UPVC locks include: UPVC broken mechanisms, upvc door may stuck, handles become loose or broken, the door catches on the frame, a window lock is jammed, a key snapped in the lock, UPVC door is not closing etc.

But these issues can be easily handled by a UPVC locksmith. No need to call a UPVC company and wait for long weeks until they replace the whole frame for you – your local residential locksmith can easily handle with this job.

Sparrow locksmith is a team of UPVC professionals who can easily copy with most common problems for UPVC door locks and window locks and can deliver fast help to any place in Northampton or in areas around Midlands.
