The right scope
Doors and Windows for your home
Doors and windows need to work reliably as well as look right. Sticking frames, draughts, damaged seals or tired glazing can make rooms less comfortable and openings harder to use. A replacement project starts with the existing opening and the way you want it to function, rather than selecting a frame on appearance alone.
The service suits homeowners replacing individual units or coordinating several openings during a renovation. Dimensions, opening direction, ventilation and internal finishes should be considered together. The surrounding wall also matters: a new frame will not resolve a problem caused by a damaged opening or an unsuitable junction.
Our window fitters are Assure certified. Aluminium doors and windows carry a 10-year guarantee, while UPVC doors and windows carry a 5-year guarantee. We discuss the material and installation scope with you so you know which guarantee applies; we do not extend those periods to unrelated products or work.
Avoid the wrong repair
What needs attention before work starts
Ordering frames before the openings and requirements have been checked can cause fitting problems or unexpected making-good work. Small differences in measurement, threshold level or opening direction can affect daily use. Agreeing these details before ordering is more useful than trying to adapt the room after installation.
Ignoring damaged seals or water entering around an opening may allow surrounding finishes to deteriorate. The route of the water needs attention, not just the visible stain. We discuss the condition of the frame and surrounding fabric before agreeing whether replacement or related repair work is appropriate.
Our process
From first conversation to completion
Step 1
Discuss the problem and visit
Start by telling us what you need from doors and windows, where the property is and what has prompted the enquiry. Describe the symptoms or the changes you want, rather than feeling you need to diagnose the job yourself. Photos and existing plans can support the conversation, but a visit helps put the work in context. We look at access, the visible condition and the surrounding areas that may be affected. If additional specialist assessment or design is needed, that should be identified before the construction scope is settled.
Step 2
Define the scope and free quote
We discuss the proposed work, the intended result and the choices that affect the quote. For doors and windows, that includes opening sizes, frame material, glazing specification, access, existing surrounds and any remedial work revealed when frames are removed. The quote is free and carries no obligation. Ask which materials, preparation, installation and making-good tasks are included so you can compare like for like. If a product or further information is still undecided, clarify it before committing. There is no fixed price list on this page because your property's requirements need to be assessed rather than guessed.
Step 3
Agree dates and the trade sequence
A small deposit secures your dates, and larger projects use stage payments as the work progresses. We discuss the sequence around the agreed scope, access and other trades. Building and plumbing are managed within one company; electrical work is coordinated through our dedicated partner. Where gas work is required, it is subcontracted. Tell us if you live in the property, need a particular route kept clear or have limited delivery space so the practical arrangements can be considered before work starts.
Step 4
Carry out the agreed work and check it
The work follows the agreed doors and windows scope and the information available for your property. If something unexpected is uncovered, discuss its effect on the plan before assuming it belongs in the original price. Checks depend on the task: an installation, repair and structural change do not have identical verification requirements. The relevant trade considers the operation, connections or completed work within its scope. Where a product has instructions or the project requires particular documentation, those should be discussed as part of the handover.
Step 5
Walk through the result and guarantee
At completion, we walk through the finished job with you and make sure you are happy with the agreed result. Use this conversation to raise questions about operation, care and any follow-up work. Aluminium doors and windows carry a 10-year guarantee; UPVC doors and windows carry a 5-year guarantee. General works carry a 1-year workmanship guarantee. Keep the agreed scope and any supplied product information so the distinction between the work and manufacturer terms stays clear. If an emergency visit only makes a situation safe, the permanent repair or making good should be discussed separately rather than treated as already completed.
A more considered job
Practical benefits, not vague promises
A scope you can make a decision on
A free quote for doors and windows lets you understand the proposed work before committing. Defining opening sizes, frame material, glazing specification, access, existing surrounds and any remedial work revealed when frames are removed helps distinguish essential work from optional choices and avoids comparing prices that cover different tasks.
Fewer disconnected trade decisions
Building and plumbing sit within the same company, with electrical work coordinated through a longstanding partner. Where the job crosses those trades, the sequence can be discussed together instead of leaving the homeowner to resolve incompatible plans after work has begun.
Attention to what sits behind the finish
The visible result is only part of doors and windows. Existing condition, access and the relationship with adjoining work influence reliability. An assessment helps identify those questions early, rather than treating a new surface or fitting as proof that every underlying issue has been resolved.
Clearer care and next steps
Knowing what was done, what needs maintaining and which guarantee applies makes the completed work easier to look after. We distinguish installation workmanship from product terms and avoid a blanket promise that every material or component will perform identically for a fixed number of years.
Service details
Planning your doors and windows work
UPVC and aluminium options
UPVC and aluminium have different frame profiles, finish options and maintenance needs. The choice should take account of the opening size, desired appearance and the product system rather than assumptions about a material. Ask which specification is included, what hardware is proposed and how the frame will meet the existing wall and finishes.
Opening styles and everyday operation
A window needs an opening arrangement that suits ventilation, access and the room layout. Doors need appropriate clearances, threshold details and a workable swing or folding direction. Furniture, steps and adjacent openings can all influence the choice. These practical details should be agreed alongside glazing and finish selections.
Installation and surrounding finishes
Removing an existing frame can reveal the condition of the opening behind it. Fixings, sealing and making good need to be considered as a complete installation. We discuss what the quote includes around internal and external finishes so there is a clear distinction between fitting the unit and additional decorating or repair work.
Your questions
Doors and Windows FAQs
How much does doors and windows cost in Sidcup?
The cost depends on opening sizes, frame material, glazing specification, access, existing surrounds and any remedial work revealed when frames are removed. We do not give an invented starting price because that could exclude work your property actually needs. A free, no-obligation quote is the appropriate next step. Describe the problem or proposed change and any products you have already chosen so we can discuss a defined scope. Comparing the included work, rather than only the total figure, helps you make a more informed decision.
How long will the doors and windows work take?
The timetable depends on the agreed scope, access, existing condition and any product or specialist requirements. We discuss dates and the sequence after assessing the job rather than promise a standard duration for every property. Tell us about any deadline and whether the home will remain occupied. Emergency attendance is a separate matter: we typically attend within 2 hours, never more than 4, but attendance does not guarantee that every repair is completed within that period.
What should I prepare before requesting a quote?
Tell us the property location, what you want to change or repair and when you first noticed the issue. Relevant photos, product details and existing drawings can help, but do not dismantle anything or enter an unsafe area to obtain them. For doors and windows, it is especially useful to explain the intended outcome and what needs to remain usable while work takes place. We can then discuss the visit and any additional information needed to define the scope.
What guarantee applies to this service?
Aluminium doors and windows carry a 10-year guarantee; UPVC doors and windows carry a 5-year guarantee. General works carry a 1-year workmanship guarantee. A guarantee is not a substitute for following the care requirements of the installed materials or equipment. Product warranties vary and must be checked against the actual supplied product; we do not invent their duration. Ask about the relevant scope when the quote is discussed, particularly where a project combines general building work with a new roof or replacement doors and windows.
How long should the completed doors and windows last?
The useful life of doors and windows depends on the frame system, exposure, hardware and maintenance. The product specification and care instructions are more useful than a universal replacement interval. During the quote and handover, ask about the particular materials, expected care and signs that deserve attention. Keeping maintenance access available and responding promptly to faults can help protect adjoining work. We avoid a blanket lifetime promise because a repair, replacement product and wider building alteration have different conditions and responsibilities.
Are emergency visits available outside normal hours?
Yes. We are open 24 hours a day, seven days a week, with typical emergency attendance within 2 hours and no more than 4. Call to describe the urgent situation rather than assume every planned building task is an emergency repair. If there is immediate danger, suspected gas escape or another serious hazard, contact the appropriate emergency service first. Any immediate make-safe work and subsequent permanent repair should be distinguished clearly.
Do you cover Sidcup and the surrounding areas?
We are based in Sidcup and cover Bexleyheath, Welling, Kidbrooke, Chislehurst, Petts Wood, Orpington, Dartford, Gravesend, Eltham, Bexley, Bromley, Crayford, Erith, Swanley. Tell us the property location when you enquire so the work can be discussed in context. The same first step applies locally: explain what you need, arrange the assessment and receive a free quote for the agreed scope. We do not invent area-specific travel charges or arrival estimates for planned work.
Who handles other trades and how are payments arranged?
Building and plumbing are in-house trades. George has 17 years of plumbing and heating experience and Jake has 20 years of building experience. Electrical work is carried out through a dedicated partner company we have worked with for over 10 years; gas work is subcontracted. A small deposit secures dates and larger projects are paid in stages. Discuss the actual stages and trade scope with the quote rather than assume a standard percentage or payment schedule.
