Internal Doors: A Complete Guide for Cornish Homes
Internal doors define the character of your home. Our complete guide covers styles, materials, finishes, hanging, and maintenance for Cornish homes.
Why Internal Doors Matter More Than You Think
Internal doors are one of the most overlooked elements of a home, yet they have an outsized impact on its character. They are the largest moving objects in most rooms, they are touched multiple times a day, and they line up in long views down hallways where any inconsistency is immediately visible. Get them right, and they unify a home; get them wrong, and they are a constant, low-level irritation.
The right internal doors suit the period and style of the home, are consistent throughout, operate smoothly, and provide the right balance of light, sound, and privacy. Choosing them is a decision worth time and thought, because they are expensive to replace and you will live with them for years.
This guide covers the key decisions in choosing and fitting internal doors, with particular attention to what works in Cornish homes of different periods.
Door Styles: Matching the Period
The style of internal door should relate to the period of the home. In Victorian and Edwardian Cornish terraces, four-panel or six-panel doors in painted softwood or oak are the classic choice, and they suit the proportions and detailing of these homes perfectly. Replacing original panel doors with modern flush doors in a period home is almost always a mistake.
In 1930s and post-war homes, two-panel doors with a taller upper panel are typical, and these suit a slightly more streamlined look. In modern homes, flush doors in painted MDF or veneered finishes give the clean, contemporary aesthetic that suits the architecture. The key is consistency — mixing styles within a home is jarring and should be avoided.
For a contemporary twist on a traditional home, ledged and braced or board doors give a rustic, characterful feel that suits country and coastal properties. These are constructed of vertical boards braced on the back, and they have an honest, hand-made quality that pairs well with exposed stone and timber floors.
Materials: Solid Wood, Engineered, or Painted
Internal doors are available in solid wood, engineered (a solid or hollow core with a veneer or painted finish), and fully painted MDF. Each has its merits. Solid wood doors are the most traditional and the most characterful, with genuine grain and weight, but they are the most expensive and the most prone to movement with humidity.
Engineered doors are the most popular choice for a balance of quality and stability. A solid engineered door has a core of blocks or particleboard with a real wood veneer face, giving the appearance of solid wood with far less tendency to warp. A hollow-core door is lighter and cheaper but less sound-insulating and less substantial in feel.
Painted MDF doors offer a flawless, contemporary finish and complete colour flexibility, and they are dimensionally stable. They are the standard choice for modern painted interiors. The quality of the finish depends on the painting process — factory-sprayed doors with multiple coats of lacquer paint give the most durable and most beautiful result.
Finishes: Painted, Veneered, or Oiled
The finish of a door determines both its appearance and its maintenance. Painted finishes are the most flexible, as they can be colour-matched to any shade and refreshed easily. They suit both traditional and contemporary interiors and are the most popular choice in Cornwall. We favour factory-sprayed lacquer paint for its hardness and flawless finish.
Veneered finishes show the natural grain of the timber and need no repainting, only occasional cleaning. They suit a warmer, more natural look and are available in a wide range of timbers. The veneer should be of a good thickness to allow for refinishing if needed; thin veneers cannot be sanded and are easily damaged.
Oiled finishes, typically on solid oak or ash doors, give the most natural look of all, with the grain fully visible and a soft, tactile surface. They need re-oiling periodically (annually in heated homes) to maintain their appearance and protection. They are beautiful but demanding, and suit homeowners who value the living quality of natural timber.
Hanging Doors Properly
A door is only as good as its hanging. A beautifully made door hung poorly will rub, stick, or gape, while a modest door hung well will operate perfectly for decades. Proper hanging starts with the lining (the frame the door sits in), which must be set perfectly plumb, level, and square — a skill that is rarer than it should be.
The door is then fitted to the lining with consistent gaps all round (typically 2–3mm), hung on three hinges for stability, and fitted with a latch or lock. The hinges should be of a quality to match the door — solid brass or stainless steel for premium doors, properly recessed and aligned. The latch should operate smoothly and close with a satisfying click rather than a slam.
Finally, the door should be adjusted to close cleanly against its stop with even pressure all round. This is the detail that separates a well-hung door from a merely fitted one, and it is worth insisting on. A door that closes properly is a pleasure to use; one that does not is a constant minor annoyance.
Sound Insulation and Privacy
Internal doors play a significant role in the sound insulation of a home. A hollow-core door does little to stop sound; a solid door, particularly a heavy one, makes a noticeable difference. For bedrooms, bathrooms, and home offices, where privacy matters, solid doors are worth the additional cost.
Beyond the door itself, the fit matters. A door with large gaps at the threshold or around the edges will leak sound regardless of its construction. We fit doors with consistent, small gaps and, where sound insulation is critical, can fit acoustic seals that close the gaps completely when the door is shut.
For the best sound insulation, the door, the lining, and the wall all need to be considered together. A solid door in a thin, uninsulated stud wall will only do so much. We are happy to advise on the most effective approach for specific rooms, balancing sound insulation with ventilation and practicality.
Fire Doors: Where They Are Required
Building regulations require fire doors in certain locations — typically on integral garages, in loft conversions, and on escape routes in multi-storey homes. Fire doors are constructed to resist fire for a specified period (commonly 30 minutes, FD30) and must be fitted with appropriate seals, hinges, and latches as a complete, certified assembly.
It is important to understand that a fire door is only effective as part of a certified installation. A fire door hung with standard hinges, without the right seals, or with an incompatible latch offers little real protection. We fit fire doors as complete certified assemblies, with all the required components, and provide the certification that building control requires.
Fire doors need not look different from standard doors. Modern FD30 doors are available in the same styles and finishes as standard doors, so a home can have consistent doors throughout while meeting all fire safety requirements. This is worth discussing early in a project so the right doors are specified from the start.
Hardware: The Details That Count
Door hardware — hinges, handles, latches, and stops — is touched and seen every day, and it is worth choosing and fitting well. Hinges should be solid, properly sized for the door's weight, and neatly recessed. Handles should be comfortable in the hand and consistent throughout the home. Latches should operate smoothly and quietly.
The style of the hardware should relate to the door and the home. Period homes suit black antique or polished brass; contemporary homes suit brushed nickel or satin chrome; coastal homes benefit from corrosion-resistant finishes. Consistency is key — mixing finishes and styles within a home looks unplanned.
We fit all hardware with care, ensuring that handles are at a consistent height, that latches are properly aligned, and that stops are fitted to prevent damage to the door and the wall. These details are small but they are the difference between doors that feel considered and doors that feel fitted.
Maintaining Internal Doors
Well-made and well-hung internal doors need little maintenance, but a little care keeps them working and looking their best. Hinges benefit from an occasional drop of light oil; latches may need adjustment as the home settles; and painted finishes should be wiped with a damp cloth rather than scrubbed.
In Cornish homes, seasonal movement is a reality. Doors may stick slightly in damp weather and gape slightly in dry weather. Minor seasonal adjustment is normal and is best addressed by a carpenter rather than by trimming the door, which can leave it gapping when the weather changes back.
With reasonable care, quality internal doors will give decades of service. The investment in good doors, well hung, is one of the most worthwhile in a home, because it is an investment you interact with every single day.
Frequently Asked Questions
Quick answers to the questions we hear most about Internal Doors: A Complete Guide for Cornish Homes.
What is the best material for internal doors?+
Engineered doors with a real wood veneer offer the best balance of quality and stability. For painted finishes, MDF is dimensionally stable and takes a flawless finish. Solid wood is characterful but prone to movement.
Do I need fire doors in my home?+
Building regulations require fire doors on integral garages, in loft conversions, and on escape routes in multi-storey homes. Fire doors must be fitted as complete certified assemblies with appropriate seals and hardware.
How do I stop my internal doors from sticking?+
Seasonal movement is normal in Cornish homes. Minor sticking in damp weather is best adjusted by a carpenter rather than trimmed, which can cause gapping when the weather dries. Ensure the lining is plumb and the gaps are consistent.
Should internal doors be consistent throughout the home?+
Yes. Consistency of style, finish, and hardware throughout a home is important, as doors line up in long views where any inconsistency is immediately visible. Mixing styles looks unplanned.
