Hainault Home Improvements
Here for the life of your door.
Your guarantee in full, how to look after your door and how to get help.

Keep your door working well, with help from the team who fitted it. Keep your order reference and product instructions somewhere easy to find.
Know what is covered.
Every installation comes with HHI’s guarantee and a 10 year insurance backed warranty from HomePro, alongside FENSA certification. Under HHI’s terms and conditions, once full payment is made, the goods we supply are guaranteed against defects in materials for these periods:
| What is covered | Guaranteed for |
|---|---|
| Frame products | 10 years |
| Glass products | 5 years |
| Dark wood and oak finish composite doors | 5 years |
| Locks, handles, hinges and other moving parts | 3 years, if maintained and fully lubricated as the manufacturer recommends |
| Commercial, rental and supply only orders | 12 months parts and labour |
Your guarantee applies once full payment is made. Late payment may result in referral to a debt recovery agency and the loss of the guarantees.
Looking after your door.
- Lubricate all moving parts, the locks and hinges, at least once a year, and more often in dusty or extreme conditions. Wipe away any excess oil, debris or dirt.
- Clean white and woodgrain finishes with a household cleaner made for UPVC surfaces. Avoid abrasive cleaners and anything containing bleach.
- Glass and energy efficient coatings are soft materials, so clean them gently. Their optical quality is guaranteed to the visual standards of the Glass and Glazing Federation.
- Use the instructions supplied for your door and hardware, never force a stiff lock, and tell HHI if the door becomes difficult to close.
What the guarantee does not cover.
- Routine cleaning, and normal cosmetic and mechanical wear and tear.
- Damage, faults or breakage caused by neglect, excessive force or not looking after the door as above.
- Work by other tradespeople on doors, windows or any products HHI supplied.
- Fitting anything electrical, such as alarms: our installers are not insured for electrical work. Relocating an existing alarm or doorbell can usually be done as a goodwill gesture.
- Condensation, mould or dampness.
If something goes wrong.
- Tell us as soon as you can, and within 7 days of first noticing a fault, so we can put it right before more damage is caused and claim from the manufacturer.
- A replacement carries the rest of the original guarantee, which always runs from the original installation date.
- We match replacement parts like for like wherever we can, but after some years an exact match cannot always be guaranteed.
- We don’t run an emergency call-out service: service visits are booked for the next available date. If you need an emergency locksmith, contact your home insurer about reimbursement.
- The guarantee is not transferable if you sell your home.
When you call, have your order reference, installation date and a description or photograph of the issue ready.
