Frequently Asked Questions — Stevenage
-
How much for a Stevenage lock change?
Single euro cylinder swap from £89. Anti-snap upgrade £119 to £149. Full BS3621 mortice on a timber door £149 to £189.
-
New-town houses have uPVC doors. What spec do you fit?
TS007 3-star anti-snap euro cylinders are the right answer for uPVC and composite. £119 typical, defeats the lock-snapping technique used in most break-ins.
-
What about the Old Town timber-doored cottages?
BS3621 5-lever mortice fits the original chase on most period doors without modification. Brass furniture stays where it is.
-
Can I have one key for everything?
Yes. Keyed-alike sets pin on site so front, back, side gate all work off a single key.
-
Insurance approval?
BS3621 on timber and TS007 3-star on uPVC are standard policy specifications. We label the receipt clearly for any claim.
-
How long is the engineer with me?
Single cylinder, around 20 minutes. Mortice change, 45 to 60. Whole house with matched keys, around two hours.
-
Do you take the old locks away?
Yes, unless you'd prefer to keep them. Old cylinders go for metal recycling.
