Composite doors have become one of the most popular choices for homeowners in Horsham who want a strong, secure, and stylish entrance. These doors are known for their durability, thermal efficiency, and attractive designs that suit both modern and traditional homes. As more people in Horsham upgrade their windows and doors, the demand for skilled companies that specialise in composite door installation continues to grow.
This guide is designed to help Horsham homeowners understand what to look for when choosing a composite door supplier and installer, and how to compare local companies with confidence.
Why Composite Doors Are So Popular in Horsham
Composite doors are designed using a blend of materials that work together to create a strong and long lasting entrance door. They typically include a solid timber core, reinforced frame structure, insulated layers, and a GRP (Glass Reinforced Plastic) skin for weather resistance.
Here are the main reasons Horsham homeowners prefer composite doors:
High Security
Composite doors are built with solid internal cores, thick frames, and multi point locking systems. This makes them far stronger than many traditional wooden or UPVC doors.
Energy Efficiency
With insulated cores and advanced sealing systems, composite doors help reduce heat loss. Homes in Horsham often feel warmer during colder months and homeowners notice a difference in their energy bills.
Weather Resistance
The GRP skin protects the door from sun fading, rain damage, and warping, which is especially useful in changing Sussex weather conditions.
Low Maintenance
Composite doors do not need sanding, painting, or varnishing. A simple wipe keeps them looking fresh.
Attractive Styles
From traditional cottage designs to sleek modern styles, composite doors come in a wide range of colours, glass patterns, and frame finishes.
Types of Companies in Horsham Offering Composite Door Installation
Horsham has a mix of different types of window and door companies. Understanding these categories helps you choose the right business for your needs.
1. Local Specialist Window and Door Companies
These companies focus on supplying and installing products such as composite doors, UPVC windows, and patio doors. They usually have experienced installers and often operate a showroom you can visit.
Many Horsham homeowners prefer established local specialists such as Window Mart, where they can view door styles in person and work with trained installers who are familiar with local property types.
2. Home Improvement Contractors
Some general home improvement businesses also offer composite door installation, although windows and doors may not be their primary focus.
3. National Brands With Local Fitters
Large UK brands sometimes promote composite doors in the Horsham area, but installation is often carried out by subcontractors. This can result in higher costs and longer waiting times.
4. Independent Joiners or Local Tradespeople
Independent tradespeople can be skilled, but they may not offer the same product range, warranties, or aftercare support as specialist companies.
For these reasons, many homeowners choose local specialist companies with showrooms and direct installation teams.
What to Look for When Comparing Window and Door Companies in Horsham
When choosing a company to install your composite door, the following factors are important.
1. Experience With Composite Door Systems
Composite doors are heavier and more complex than traditional doors. A good installer understands frame structure, locking alignment, and sealing methods. Ask whether the company uses its own trained installers.
Local businesses such as Window Mart typically employ dedicated installation teams, which helps ensure consistent workmanship and accountability.
2. Door Quality and Range of Styles
A reliable company should offer a wide choice of styles, including:
- Timber core composite doors
- Heritage style designs
- Contemporary glazed doors
- Cottage and traditional panels
- Premium locking systems
A broader range makes it easier to find a door that suits your Horsham property.
3. Local Knowledge and Installation Experience
Horsham includes a variety of property styles such as period cottages, Victorian terraces, modern developments, and rural homes. Companies that regularly work in the area understand common challenges and frame requirements.
4. Showroom Access for Viewing Doors
Many homeowners prefer to see composite doors before making a decision. A showroom allows you to compare colours, finishes, glazing, and door hardware in person.
Window Mart’s local showroom gives Horsham homeowners the opportunity to view composite door options first hand rather than relying only on brochures or online images.
5. Transparent Pricing and No Sales Pressure
The best companies provide clear quotes, straightforward explanations, and allow homeowners to take time to decide without pressure.
6. Installation Quality and Aftercare
Good installers pay attention to alignment, sealing, and finishing. After installation, a reliable company will explain maintenance and provide warranty details.
