Why fit a window restrictor
Most people ask for these for one of two reasons. Either there are young children in the house and a window that opens too wide, or it is an upper-floor flat where a window is an easy way in for someone who should not be there. A restrictor sorts both. It lets the window open enough for air but stops it swinging wide, and where the room needs a fire escape route we fit the type with a key release so the window can still be opened fully in an emergency. Tell me which windows and I will match the restrictor to the frame, whether it is uPVC, timber or metal.
Landlords come to me a fair bit for this, because restrictors on upper windows are a common condition on tenancy and insurance. If you have several windows to do, say so up front and I will price the lot together rather than one at a time, which usually works out better. The window lock repair and key-locking handle side of things often gets looked at during the same visit, so if a handle is loose or a catch has gone it makes sense to sort it while I am there.
I cover Southampton, the whole Waterside, Hythe, Holbury, Fawley, Blackfield, Dibden, Marchwood, Totton and out into the New Forest. Fitting is done properly with a 12-month guarantee on the parts, and there is a free home security check on offer if you want the rest of the house looked over at the same time. No call-out fee, no VAT, and I tell you the price straight before I start.

Common questions
How much does window restrictor installation cost in Southampton?
From £75, and typically £75 to £110 depending on how many windows you have and the type of frame. If you have several to do, tell me up front and I will price the lot together rather than one at a time, which usually works out better. No call-out fee, no VAT, and I tell you the price straight before I start. The price I quote is the price you pay.
Can I still open the window fully in a fire if a restrictor is fitted?
Yes, where a room needs a fire escape route I fit the type with a key release. That lets the window open enough for air day to day but stops it swinging wide, and in an emergency the key release means it can still be opened fully. Tell me which rooms need an escape route and I will match the right restrictor to the frame, whether it is uPVC, timber or metal.
Do you fit window restrictors for landlords and upper-floor flats?
Yes, landlords come to me a fair bit for this, because restrictors on upper windows are a common condition on tenancy and insurance. If you have several windows across a property, say so up front and I will price them together rather than one at a time. I cover Southampton, Hythe, Holbury, Fawley, Marchwood, Totton and out into the New Forest, and every part fitted comes with a 12-month guarantee.
Can you sort a loose handle or broken catch while fitting restrictors?
Yes, no drama. The window lock repair and key-locking handle side of things often gets looked at during the same visit, so if a handle is loose or a catch has gone it makes sense to sort it while I am there. Window lock repair or replace starts from £80. There is also a free home security check on offer if you want the rest of the house looked over at the same time.
