What does NLL Måleri’s window restoration include?

Restoration may include preparation, repairs, putty work and painting. Condition and construction determine what is needed.

Before requesting a quote, describe worn or damaged parts:

peeling or detached paint
soft or damaged timber
cracked or loose putty
damaged glazing beads
which sash and frame sides need treatment

NLL also offers window and door painting with repairs. Describe damage when contacting us so the enquiry has the right scope. Do not automatically use painting-with-repair prices for full restoration.

Points to clarify before window restoration
Part	Question before quoting	Why it is needed
Paint	Which surfaces need preparation and painting?	Define the work
Timber	Is sash or frame damaged?	Assess repair needs
Putty	Which glazing rebates need attention?	Clarify scope
Glass and beads	Are any parts damaged?	Assess possible extras
Surface treatment	Which sides and system will be used?	Compare identical work

Also state the floor and any difficult access. The quote must include material choices, access and extras. Request a window restoration quote and describe the help you need.

How is a timber window restored step by step?

Restoration begins with condition assessment. Preparation, repairs and finishing are then planned around construction and the products to use.

The table outlines possible tasks, not product instructions. Putty work, priming and painting must suit the chosen system.

Possible tasks: methods adapted to the window
Stage	Task	Considerations
1	Assessment	Window condition and construction
2	Preparations	Access and protection of surrounding surfaces
3	Preparation	Cleaning and loose-paint removal
4	Repairs	Damaged parts assessed before finishing
5	Putty work and priming	Sequence and products according to the chosen system
6	Painting	Surface and drying times according to product instructions

Check drying and recoating times for the product used. Beckers’ window putty instructions state conditions for that putty; the same times do not automatically apply to others. Also read our guide to window putty repairs.

Describe window numbers, condition and property location.

When should you restore rather than replace a window?

Compare restoration and replacement by damage, function and cost. Age alone does not determine suitability.

Also consider function and house character. Avoid deciding solely from a generic unit price.

Questions before choosing restoration or replacement
Starting point	What needs assessment?	Decision information
Worn paint or putty	What maintenance is needed?	Condition and proposed action
Damaged timber	Can parts be repaired?	Assessment of damage extent
Extensive damage	What do restoration and replacement involve?	Comparable quotes
Draughts or energy questions	How do windows and ventilation work together?	Assessment of the complete solution
Older windows	Which qualities should be preserved?	House character and heritage value

Boverket’s guidance on window restoration and replacement covers condition, energy performance, costs and heritage value. Replacement can also affect ventilation and appearance. Request assessment before choosing action.

What needs assessing when windows have timber rot?

Suspected rot must be assessed before painting. Its extent determines repairable parts and whether replacement is needed.

Beckers’ window painting advice covers checking for rot and addressing damage before painting. The appropriate repair needs on-site assessment.

State damage location: sash, frame or around glass. Send an overview and close-up when contacting us. Photos help describe the issue but do not replace timber-condition assessment.

Also, window and door painting with repairs is among NLL’s services. The distinction from full restoration must be described in your quote.

What does window restoration cost, and does ROT apply?

Full restoration requires individual pricing. State window numbers, condition and parts needing attention when requesting a quote.

Distinguish full restoration from painting with repairs when comparing prices. Request separate labour, materials, VAT and extras so quotes cover identical work.

Prices to distinguish before quoting
Work type	How price is determined	Important scope distinction
Full window restoration	Quote for the specific job	Scope and materials need specifying
Window painting with repairs	See separate price guide	The guide does not automatically cover full restoration
Extras and access	Clarified in the quote	Do not assume glass replacement or scaffolding is included

ROT may cover up to 30% of eligible labour including VAT if conditions are met. Materials and travel are excluded. Tax paid and remaining allowance affect entitlement. Read the Swedish Tax Agency's conditions for the ROT tax deduction.

See labour prices for windows and doors with repairs if comparing that service. These do not quote full restoration. For your window restoration, you can describe the job and request a quote.

Frequently asked questions

Is restoring old windows worthwhile compared with replacement?

It can be, but the choice depends on condition, function and alternative costs. Compare quotes for the same needs and consider house character. Restoration is not always cheapest.

How long does a restored window last?

There is no universal maintenance interval. Request care instructions for the chosen paint and putty system and regularly check paint, putty and exposed timber.

Does ROT apply to window restoration?

Eligible work may qualify if you and the home meet conditions. Tenant-owned apartments have particular restrictions: exterior window work does not have the same entitlement as eligible interior work. Read the Swedish Tax Agency’s window and door rules.
